CVE-2011-5124 describes a stack-based buffer overflow vulnerability in the BCAAA component of Blue Coat ProxySG (versions 4.2.3 through 6.1) and ProxyOne. This critical flaw allows unauthenticated remote attackers to execute arbitrary code by sending a large packet to the synchronization port (16102/tcp). With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. While not listed in CISA KEV, exploit code is publicly available via a Metasploit module, though there is no indication of active exploitation or significant community discussion.
