CVE-2009-1291

28
FAUCET Score

CVE-2009-1291 describes a critical stack-based buffer overflow vulnerability affecting TIBCO SmartSockets, RTworks, and Enterprise Message Service (EMS) products. This flaw allows unauthenticated remote attackers to execute arbitrary code by sending specially crafted "inbound data" to vulnerable services, such as the UDP interface of RTserver or the TCP stream of tibemsd. With a CVSS score of 10.0, this vulnerability is highly severe due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its age and high severity, there is no public exploit intelligence, such as Metasploit or ExploitDB modules, and it is not listed on the CISA KEV catalog, suggesting it is not actively exploited in the wild.
