CVE-2011-5007 describes a critical stack-based buffer overflow in the CmpWebServer component of 3S CoDeSys 3.4 SP4 Patch 2 and earlier, including its use in the ABB AC500 PLC. This vulnerability allows unauthenticated remote attackers to execute arbitrary code by sending a crafted, excessively long URI to TCP port 8080. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, public exploit modules exist for Metasploit and ExploitDB, indicating readily available exploit code, though community discussion and media coverage are minimal.
