CVE-2024-30122Network attack vector

Browser protection weakening via missing HTTP headers

Published Oct 23, 2024 · Updated Nov 25, 2024

Missing security headers in HCL Sametime 12.0.2 and earlier allow remote attackers to weaken browser-enforced protections. Web-service responses omit unspecified security-related HTTP headers, causing browsers to apply less restrictive defaults for the policies those headers control. Exploitation requires user interaction and high-complexity conditions; HCL has not identified the omitted headers or a specific downstream attack.
