CVE-2023-24453: 
Java vulnerability analysis and mitigation

Jenkins TestQuality Updater Plugin version 1.3 and earlier contains a missing permission check vulnerability (CVE-2023-24453) that was disclosed on January 24, 2023. This vulnerability affects the form validation method implementation in the plugin, allowing attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified username and password (Jenkins Advisory).

The vulnerability has a CVSS v3.1 Base Score of 6.5 (Medium) with vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N. The issue stems from insufficient permission checks in methods implementing form validation, which allows authenticated users with basic read access to bypass security controls (NVD).

When exploited, this vulnerability allows attackers with Overall/Read permission to connect to arbitrary URLs using attacker-specified credentials. This could potentially lead to unauthorized access to external systems and exposure of sensitive information (Jenkins Advisory).

The vulnerability requires an attacker to have Overall/Read permission in Jenkins, which is a relatively low privilege level. The attack can be executed remotely through the plugin's form validation functionality (Jenkins Advisory).

As of the advisory publication date, no official fix is available for this vulnerability. Users of the TestQuality Updater Plugin should consider restricting access to the plugin's functionality and carefully monitor its usage (Jenkins Advisory).
