CVE-2013-2255

20
FAUCET Score

CVE-2013-2255 describes a critical vulnerability in OpenStack Keystone 2013, OpenStack Compute 2013.1, and potentially other OpenStack components, where HTTPS connections fail to validate server-side SSL certificates. This medium-severity vulnerability (CVSS 5.9) allows an unauthenticated attacker to compromise data integrity with high impact by intercepting and manipulating traffic due to the absence of proper certificate validation. Despite its potential impact, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
