#vulnerability

Improper Input Validation vulnerability in Apache Zeppelin. By adding relative path indicators (e.g `..`), attackers can see the contents for any files in the filesystem that the server account can access.  This issue affects Apache Zeppelin from 0.9.0 before 0.11.0. Users are recommended to upgrade to version 0.11.0, which fixes the issue.

A flaw was found in` JwtValidator.resolvePublicKey` in JBoss EAP, where the validator checks jku and sends a HTTP request. During this process, no whitelisting or other filtering behavior is performed on the destination URL address, which may result in a server-side request forgery (SSRF) vulnerability.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass RSA signature verification on a vulnerable system.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is sensitive information.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**How could an attacker exploit this vulnerability?** To successfully exploit this vulnerability, the target server must be configured to allow remote activation of the COM object. In addition, the attacker must have sufficient user privileges on that server.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker would only be able to delete targeted files on a system.
