Deeper analysis
CVE-2024-43810 is a reflected cross-site scripting vulnerability (CWE-79) affecting the AWS Core plugin in JetBrains TeamCity versions prior to 2024.07.1. The flaw carries a CVSS 3.1 score of 4.6 and stems from insufficient input sanitization that allows malicious scripts to be reflected back to users through the plugin's web interface.
An attacker with low-privileged authenticated access can craft a malicious request that triggers the reflected XSS when a victim user interacts with the link. Successful exploitation yields limited read and write access within the victim's session context but does not permit full account takeover or denial of service.
The official JetBrains security advisory at https://www.jetbrains.com/privacy-security/issues-fixed/ states that the issue is resolved in TeamCity 2024.07.1; administrators are advised to upgrade promptly to eliminate the reflected XSS vector in the AWS Core plugin.
The associated EPSS score has remained flat at 0.4762 with no material upward trajectory observed after disclosure.
