CVE-2008-7297: Opera cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-...

Security readout for executives and security teams

This CVE describes an old Opera browser cookie-integrity weakness. A network attacker who can interfere with unencrypted HTTP traffic could overwrite or delete cookies used by HTTPS sessions, potentially disrupting or influencing authenticated web activity. The source bundle does not identify affected Opera versions, a patch level, CVSS score, or active exploitation. Exposure is most plausible in legacy Opera browser use and applications that still allow HTTP access alongside HTTPS. The provided CVE data does not name specific versions or platforms, so asset teams should treat exposure as uncertain until browser inventories and vendor history are checked. Handle as a legacy-browser and web-configuration hygiene issue unless evidence shows Opera use in sensitive environments. Prioritize discovery first, then remove unsupported browsers and strengthen HTTPS-only application posture. Mitigation focus: Check Opera or vendor guidance for affected versions and fixed builds.; Retire or block unsupported legacy Opera browsers in managed environments.; Enforce HTTPS and HSTS with includeSubDomains where appropriate..
