**XSS vulnerability in bundled email templates in Email Extension Plugin**

**SECURITY-2931 / CVE-2023-25763**  
**Severity (CVSS):** High  
**Affected plugin: email-ext**  
**Description:**

Email Extension Plugin bundled multiple preconfigured templates for notification emails. The Email Template Testing feature can be used to see what these and other templates would look like based on a given build.

Email Extension Plugin 2.93 and earlier does not escape various fields included in those email templates, like build display name, user display name, and the names of tests.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control affected fields.

Email Extension Plugin 2.93.1 escapes affected fields in bundled email templates.

**Stored XSS vulnerability in custom email templates in Email Extension Plugin**

**SECURITY-2934 / CVE-2023-25764**  
**Severity (CVSS):** High  
**Affected plugin: email-ext**  
**Description:**

Email Extension Plugin allows defining custom email templates using Config File Provider plugin as Jelly or Groovy files. The Email Template Testing feature can be used to see what these templates would look like based on a given build by specifying the managed: name prefix.

Email Extension Plugin 2.93 and earlier does not escape, sanitize, or sandbox rendered email template output or log output generated during template rendering.

This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to create or change custom email templates.

Email Extension Plugin 2.93.1 renders email template previews inside a sandboxed iframe.

**Script Security sandbox bypass vulnerability in Email Extension Plugin**

**SECURITY-2939 / CVE-2023-25765**  
**Severity (CVSS):** High  
**Affected plugin: email-ext**  
**Description:**

Email Extension Plugin allows defining custom email templates using Config File Provider plugin as Jelly or Groovy files. When defined inside a folder, email templates need to be subject to Script Security protection (sandboxed execution or full-script approval).

In Email Extension Plugin 2.93 and earlier, templates defined inside a folder were not subject to Script Security protection.

This vulnerability allows attackers able to define email templates in folders to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.

Email templates defined in folders are subject to sandbox protection in Email Extension Plugin 2.93.1.

**Missing permission checks in Azure Credentials Plugin allow enumerating credentials IDs**

GHSA-76r7-h46w-463r: Cross Site Scripting (XSS) in Model\DataObject\Data\UrlSlug

OX App Suite suffers from cross site scripting and server-side request forgery vulnerabilities.

Internal reference: OXUIB-1795  
Vulnerability type: CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS))  
Component: backend  
Report confidence: Confirmed  
Solution status: Fixed by Vendor  
Last affected revision: OX App Suite backend 7.10.5-rev50, OX App Suite backend 7.10.6-rev29  
First fixed revision: OX App Suite backend 7.10.5-rev51, OX App Suite backend 7.10.6-rev30  
Discovery date: 2022-07-29  
Solution date: 2022-10-21  
Disclosure date: 2023-02-08  
CVE: CVE-2022-37306  
CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

Details:  
XSS using "upsell" triggers. Non-alphanumeric content can be injected by the user as JS content for the "upsell" module. As a result, the code will be executed during subsequent logins and opening the "Portal" application, enabling a persistent cross-site scripting attack vector.

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. No publicly available exploits are known.

Solution:  
We improved the allow-list sanitizing algorithm to deal with non-alphanumeric code.

CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

Details:  
XSS using "upsell ads". HTML content can be injected by the user as JS content for the "upsell ads" module. As a result, the code will be executed during subsequent logins and opening the "Portal" application, enabling a persistent cross-site scripting attack vector.

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. No publicly available exploits are known.

Solution:  
We improved the sanitization process for upsell ads.

CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

Details:  
"Tracking" features can be used to inject arbitrary script code. In case activity tracking adapters are enabled but not defined, users can use jslob to define own tracking settings for an account. This allows adding arbitrary values to trigger a specific URL or load a library.

Risk:  
Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface (e.g. redirecting to a third-party site). To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. No publicly available exploits are known.

Solution:  
We made the related jslob configuration endpoint read-only for users.

CVE: CVE-2022-43698  
CVSS: 5.0 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N)

Details:  
SSRF using POP3 account updates. When changing a valid external POP3 mail account as a user, the operation to update the accounts settings did not consider deny-list values.

Risk:  
Server-initiated requests can be directed to internal resources that are restricted based on deny-list settings. This can be used to determine "internal" addresses and services, depending on measurement and content of error responses. While no data of such services can be exfiltrated, the risk is a violation of perimeter based security policies. No publicly available exploits are known.

Solution:  
We now check compliance with existing deny-list content when updating POP3 mail accounts.

CVSS: 5.0 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N)

Details:  
Mail account discovery can be abused for SSRF. The external E-Mail autodiscovery feature performs connections checks based on the E-Mail addresses host-part. Those do not take existing deny-lists into respect, allowing attackers with access to DNS records of a domain to redirect requests to illegal addresses.

Risk:  
Server-initiated requests can be directed to internal resources that are restricted based on deny-list settings. This can be used to determine "internal" addresses and services, depending on measurement and content of error responses. While no data of such services can be exfiltrated, the risk is a violation of perimeter based security policies. No publicly available exploits are known.

Solution:  
We check for compliance with existing deny-list content when performing mail account autodiscovery.

CVSS: 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

Details:  
Apache Commons Text Update. A critical vulnerability at the Apache Commons Text library has been identified, which is used by OX App Suite and OX Documents. However, our products do not directly use the vulnerable StringSubstitutor class. Based on current knowledge that means our products are not vulnerable.

Risk:  
Remote Code Execution, see CVE-2022-42889. No publicly available exploits are known.

Solution:  
We provided a update for this library to resolve the risk as a precaution, in case custom implementations use the vulnerable class.
