CVE-2013-4584

CVE-2013-4584 describes a medium-severity vulnerability in Perdition before version 2.2, specifically affecting its STARTTLS IMAP and POP server functionality. The flaw stems from the ssl_outgoing_ciphers setting not being applied to STARTTLS connections, leading to weak security for outbound connections. While the attack vector is network-based with high attack complexity, a successful exploit could result in high integrity impacts, though confidentiality and availability are not affected. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
