Deeper analysis
CVE-2024-43807 is a stored cross-site scripting vulnerability (CWE-79) affecting the Clouds page in JetBrains TeamCity versions prior to 2024.07.1. The flaw carries a CVSS 3.1 base score of 4.6 and permits multiple instances of persistent XSS injection through the affected component.
An attacker with low-privileged authenticated access can supply malicious input that is stored and later rendered for other users. Successful exploitation requires the victim to interact with the page and can result in limited disclosure or modification of information within the TeamCity instance.
The vendor advisory at https://www.jetbrains.com/privacy-security/issues-fixed/ identifies the issue among resolved security problems and states that upgrading to TeamCity 2024.07.1 or later eliminates the vulnerability.
