CVE-2023-46179Network attack vector

Session cookie disclosure via missing Secure attribute

Published Mar 15, 2024 · Updated Aug 2, 2024

Sensitive-cookie exposure in IBM Sterling Secure Proxy 6.0.3 and 6.1.0 allows remote attackers to obtain session cookies over HTTP. The web session and authorization-token response logic emits sensitive cookies without the Secure attribute, allowing browsers to attach them to plaintext HTTP requests. Exploitation requires user interaction with an attacker-controlled HTTP link and network access sufficient to observe the resulting cleartext traffic.
