What is CVE-2013-7469?

Seafile, up to version 6.2.11, implements a flawed encryption mechanism by consistently using the same Initialization Vector (IV) in Cipher Block Chaining (CBC) mode. This predictable use of the IV significantly increases the risk of successful chosen-plaintext and dictionary attacks, jeopardizing the confidentiality of private data encrypted under this scheme. Users of affected versions should consider upgrading to mitigate this security risk.
