CVE-2015-4555

21
FAUCET Score

CVE-2015-4555 describes a buffer overflow vulnerability in the HTTP administrative interface of several TIBCO products, including Rendezvous, Rendezvous Network Server, Substation ES, and Messaging Appliance, across various daemon and agent components. This flaw allows unauthenticated remote attackers to trigger a denial of service or potentially execute arbitrary code. With a CVSS score of 7.5, it is considered highly severe due to its network-based attack vector and low attack complexity, leading to potential confidentiality, integrity, and availability impacts. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
