CVE-2024-23559Network attack vector

Browser data exposure and modification via obsolete header

Published Apr 15, 2024 · Updated Dec 4, 2024

Improper HTTP response handling in HCL DevOps Deploy allows remote attackers to expose or modify browser data through an obsolete header. The server emits the obsolete header, but HCL has not disclosed its name, the response path that adds it, or the browser behavior it triggers. Exploitation is unauthenticated over the network and requires user interaction; HCL's scoring limits the result to browser-side data disclosure and modification, with no service interruption.
