CVE-2013-7469

CVE-2013-7469 describes a critical vulnerability in Seafile versions up to 6.2.11, where the software consistently reuses the same Initialization Vector (IV) when encrypting private data using Cipher Block Chaining (CBC) mode. This flaw significantly lowers the bar for attackers to perform chosen-plaintext or dictionary attacks, potentially compromising the confidentiality of sensitive information. With a CVSS v3 score of 7.5 (High), the vulnerability is network-exploitable with low attack complexity and no user interaction required, leading to high confidentiality impact. Despite its severity, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
