**Recommended Actions for Products:**  
Avaya strongly recommends following networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but the System Product operating system or application should not be modified unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

**CVSS Scoring and Metrics:**

Avaya uses the Common Vulnerability Scoring System (CVSS) base score and metrics as reported by the vendor for the affected component(s) or by the National Institute of Standards and Technology in the National Vulnerability Database. In some cases, such as where CVSS information is not available from the vendor or NIST, Avaya will calculate the CVSS base score and metrics. Customers are encouraged to calculate the Temporal and Environmental CVSS scores to determine how the vulnerability could affect their specific implementation or environment. For more information on CVSS and how the score is calculated, see Common Vulnerability Scoring System: Specification Document.

CVE-2020-7032: ASA-2020-153

Axios NPM package 0.21.0 contains a Server-Side Request Forgery (SSRF) vulnerability where an attacker is able to bypass a proxy by providing a URL that responds with a redirect to a restricted host or IP address.

**Describe the bug**

In cases where axios is used by servers to perform http requests to user-supplied urls, a proxy is commonly used to protect internal networks from unauthorized access and SSRF. This bug enables an attacker to bypass the proxy by providing a url that responds with a redirect to a restricted host/ip.

**To Reproduce**

The following code spawns a proxy server that _always_ responds with a 302 redirect, so requests should never reach the target url, however, axios is only reaching the proxy once, and bypassing the proxy after the redirect response.

https://runkit.com/embed/1df5qy8lbgnc

const axios \= require('axios')
const http \= require('http')

const PROXY\_PORT \= 8080

// A fake proxy server
http.createServer(function (req, res) { 
    res.writeHead(302, {location: 'http://example.com'})
    res.end()
  }).listen(PROXY\_PORT)

axios({
  method: "get",
  url: "http://www.google.com/",
  proxy: {
    host: "localhost",
    port: PROXY\_PORT,
  },
})
.then((r) \=> console.log(r.data))
.catch(console.error)

The response is the rendered html of _http://example.com_

**Expected behavior**

_All_ the requests should pass via the proxy. In the provided scenario, there should be a redirect loop.

**Environment**

*   Axios Version \[0.21.0\]
*   Node.js Version \[v12.18.2\]

**Additional context/Screenshots**

Add any other context about the problem here. If applicable, add screenshots to help explain.

This advisory announces vulnerabilities in the following Jenkins deliverables:

*   Active Directory Plugin
*   Static Analysis Utilities Plugin
*   Ansible Plugin
*   AppSpider Plugin
*   AWS Global Configuration Plugin
*   Azure Key Vault Plugin
*   FindBugs Plugin
*   Kubernetes Plugin

**Descriptions****Login allowed with hardcoded password by Active Directory Plugin**

**SECURITY-2117 / CVE-2020-2299**  
**Severity (CVSS):** Critical  
**Affected plugin: active-directory**  
**Description:**

Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode.

The LDAP-based mode in Active Directory Plugin 2.19 and earlier shares code between user lookup and user authentication and distinguishes these behaviors through the use of a magic constant used in place of a real password. This allows attackers to log in as any user if the magic constant is used as the password in Active Directory Plugin 2.19 and earlier.

Active Directory Plugin 2.20 no longer uses a magic constant to distinguish between user lookup and user authentication.

**Login allowed with empty password by Active Directory Plugin**

**SECURITY-2099 / CVE-2020-2300**  
**Severity (CVSS):** High  
**Affected plugin: active-directory**  
**Description:**

Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode.

The Windows/ADSI mode does not specifically prohibit use of empty passwords in Active Directory Plugin 2.19 and earlier. If the Active Directory server allows the unauthenticated bind operation, this allows attackers to log in to Jenkins as any user by providing an empty password.

Active Directory Plugin 2.20 prohibits the use of an empty password to log in.

**Authentication cache in Active Directory Plugin allows logging in with any password**

**SECURITY-2123 / CVE-2020-2301**  
**Severity (CVSS):** High  
**Affected plugin: active-directory**  
**Description:**

Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode. Optionally, to reduce lookup time, a cache can be configured to remember user lookups and user authentications.

In Active Directory Plugin 2.19 and earlier, when run in Windows/ADSI mode, the provided password was not used when looking up an applicable cache entry. This allows attackers to log in as any user using any password while a successful authentication of that user is still in the cache.

As a workaround for this issue, the cache can be disabled.

Active Directory Plugin 2.20 includes the provided password in cache entry lookup.

Additionally, the Java system property hudson.plugins.active_directory.CacheUtil.noCacheAuth can be set to true to no longer cache user authentications.

**Missing permission check in Active Directory Plugin allows accessing domain health check page**

**SECURITY-1999 / CVE-2020-2302**  
**Severity (CVSS):** Medium  
**Affected plugin: active-directory**

This allows attackers with Overall/Read permission to access the domain health check diagnostic page.

Active Directory Plugin 2.20 requires Overall/Administer permission to access the domain health check diagnostic page.

**CSRF vulnerability in Active Directory Plugin**

**SECURITY-2126 / CVE-2020-2303**  
**Severity (CVSS):** Medium  
**Affected plugin: active-directory**  
**Description:**

Active Directory Plugin 2.19 and earlier does not require POST requests for multiple HTTP endpoints implementing connection and authentication tests, resulting in cross-site request forgery (CSRF) vulnerabilities.

This vulnerability allows attackers to perform connection tests, connecting to attacker-specified or previously configured Active Directory servers using attacker-specified credentials.

Active Directory Plugin 2.20 requires POST requests for the affected HTTP endpoints.

**XXE vulnerability in Subversion Plugin**

**SECURITY-2145 / CVE-2020-2304**  
**Severity (CVSS):** High  
**Affected plugin: subversion**  
**Description:**

Subversion Plugin 2.13.1 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Subversion Plugin 2.13.2 disables external entity resolution for its XML parser.

**XXE vulnerability in Mercurial Plugin**

**SECURITY-2115 / CVE-2020-2305**  
**Severity (CVSS):** High  
**Affected plugin: mercurial**  
**Description:**

Mercurial Plugin 2.11 and earlier does not configure its XML changelog parser to prevent XML external entity (XXE) attacks.

This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

**Descriptions****Improper authorization due to caching in Role-based Authorization Strategy Plugin**

**SECURITY-1767 / CVE-2020-2286**  
**Severity (CVSS):** High  
**Affected plugin: role-strategy**  
**Description:**

Role-based Authorization Strategy Plugin 2.12 and newer uses a cache to speed up permission lookups.

In Role-based Authorization Strategy Plugin 3.0 and earlier this cache is not invalidated properly when an administrator changes the permission configuration. This can result in permissions being granted long after the configuration was changed to no longer grant them.

Role-based Authorization Strategy Plugin 3.1 properly invalidates the cache on configuration changes.

**Request logging could be bypassed in Audit Trail Plugin**

**SECURITY-1815 / CVE-2020-2287**  
**Severity (CVSS):** Medium  
**Affected plugin: audit-trail**  
**Description:**

Audit Trail Plugin logs requests whose URL path matches an admin-configured regular expression.

A discrepancy between the behavior of the plugin and the Stapler web framework in parsing URL paths allows attackers to craft URLs that would bypass request logging in Audit Trail Plugin 3.6 and earlier. This only applies to Jenkins 2.227 and earlier, LTS 2.204.5 and earlier, as the fix for SECURITY-1774 prohibits dispatch of affected requests.

Audit Trail Plugin 3.7 processes request URL paths the same way as the Stapler web framework.

**Incorrect default pattern in Audit Trail Plugin**

**SECURITY-1846 / CVE-2020-2288**  
**Severity (CVSS):** Medium  
**Affected plugin: audit-trail**  
**Description:**

Audit Trail Plugin uses regular expressions to match requested URLs whose dispatch should be logged.

In Audit Trail Plugin 3.6 and earlier, the default regular expression pattern could be bypassed in many cases by adding a suffix to the URL that would be ignored during request handling.

Audit Trail Plugin 3.7 changes the default regular expression pattern so that it allows for arbitrary suffixes. It automatically will replace previous default patterns with the new, more complete default pattern.

Additionally, an administrative monitor is shown if a user-specified pattern is found to be bypassable through crafted URLs and form validation was improved to recognize patterns that would not match requests with arbitrary suffixes.

**Stored XSS vulnerability in Active Choices Plugin**

**SECURITY-1954 / CVE-2020-2289**  
**Severity (CVSS):** High  
**Affected plugin: uno-choice**  
**Description:**

Active Choices Plugin 2.4 and earlier does not escape the name and description of build parameters.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.

Active Choices Plugin 2.5 escapes the name of build parameters and applies the configured markup formatter to the description of build parameters.

**Stored XSS vulnerability in Active Choices Plugin**

**SECURITY-2008 / CVE-2020-2290**  
**Severity (CVSS):** High  
**Affected plugin: uno-choice**  
**Description:**

Active Choices Plugin 2.4 and earlier does not escape List and Map return values of sandboxed scripts for _Reactive Reference Parameter_.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure permission.

This issue is caused by an incomplete fix for SECURITY-470.

Active Choices Plugin 2.5 escapes all legal return values of sandboxed scripts.

**Password stored in plain text by couchdb-statistics Plugin**

**SECURITY-2065 / CVE-2020-2291**  
**Severity (CVSS):** Low  
**Affected plugin: couchdb-statistics**  
**Description:**

couchdb-statistics Plugin 0.3 and earlier stores its server password unencrypted in its global configuration file org.jenkinsci.plugins.couchstats.CouchStatsConfig.xml on the Jenkins controller as part of its configuration.

This password can be viewed by users with access to the Jenkins controller file system.

couchdb-statistics Plugin 0.4 stores its server password encrypted once its configuration is saved again.

**Stored XSS vulnerability in Release Plugin**

**SECURITY-1928 / CVE-2020-2292**  
**Severity (CVSS):** High  
**Affected plugin: release**  
**Description:**

Release Plugin 2.10.2 and earlier does not escape the release version in the badge tooltip.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Release/Release permission.

As of publication of this advisory, there is no fix.

**Arbitrary file read vulnerability in Persona Plugin**

**SECURITY-2046 / CVE-2020-2293**  
**Severity (CVSS):** Medium  
**Affected plugin: persona**  
**Description:**

Persona Plugin 2.4 and earlier allows users with Overall/Read permission to read arbitrary files on the Jenkins controller.

As of publication of this advisory, there is no fix.

**CSRF vulnerability and missing permission checks in Maven Cascade Release Plugin**

**SECURITY-2049 / CVE-2020-2294 (permission check), CVE-2020-2295 (CSRF)**  
**Severity (CVSS):** Medium  
**Affected plugin: maven-release-cascade**  
**Description:**

Maven Cascade Release Plugin 1.3.2 and earlier does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read permission to start cascade builds and layout builds, and reconfigure the plugin.

Additionally, these endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

As of publication of this advisory, there is no fix.

**CSRF vulnerability in Shared Objects Plugin**

**SECURITY-2052 / CVE-2020-2296**  
**Severity (CVSS):** Medium  
**Affected plugin: shared-objects**  
**Description:**

Shared Objects Plugin 0.44 and earlier does not require POST requests for an HTTP endpoint, resulting in a cross-site request forgery (CSRF) vulnerability.

This vulnerability allows attackers to configure shared objects.

As of publication of this advisory, there is no fix.

**Access token stored in plain text by SMS Notification Plugin**

**SECURITY-2054 / CVE-2020-2297**  
**Severity (CVSS):** Low  
**Affected plugin: sms**  
**Description:**

SMS Notification Plugin 1.2 and earlier stores an access token unencrypted in its global configuration file com.hoiio.jenkins.plugin.SMSNotification.xml on the Jenkins controller as part of its configuration.

This access token can be viewed by users with access to the Jenkins controller file system.

As of publication of this advisory, there is no fix.

**XXE vulnerability in Nerrvana Plugin**

**SECURITY-2097 / CVE-2020-2298**  
**Severity (CVSS):** High  
**Affected plugin: nerrvana-plugin**  
**Description:**

Nerrvana Plugin 1.02.06 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.

This allows attackers with Overall/Read permission to have Jenkins parse a crafted HTTP request with XML data that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

Additionally, XML parsing is exposed as a form validation endpoint that does not require POST requests, allowing exploitation by users without Overall/Read permission via CSRF.

As of publication of this advisory, there is no fix.

CVE-2020-2296: Jenkins Security Advisory 2020-10-08

Jenkins Release Plugin 2.10.2 and earlier does not escape the release version in badge tooltip, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Release/Release permission.

CVE-2020-2292: Jenkins Security Advisory 2020-10-08

An issue was discovered in Gradle Enterprise 2018.5 - 2020.2.4. When configuring Gradle Enterprise to integrate with a SAML identity provider, an XML metadata file can be uploaded by an administrator. The server side processing of this file dereferences XML External Entities (XXE), allowing a remote attacker with administrative access to perform server side request forgery.
