CVE-2014-5386 describes a vulnerability in the mcrypt_create_iv function within Facebook's HipHop Virtual Machine (HHVM) before version 3.3.0. This flaw stems from the function's failure to properly seed its random number generator, leading to the generation of predictable initialization vectors (IVs). Rated with a CVSS score of 5.0, this vulnerability allows remote attackers to potentially compromise cryptographic protections due to the use of a single, easily guessable IV, resulting in a partial impact to integrity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
