Security News > 2020 > August > Exploits for vBulletin zero-day released, attacks are ongoing
The fix for CVE-2019-16759, a remote code execution vulnerability in vBulletin that was patched in September 2019, is incomplete, security researcher Amir Etemadieh has discovered.
It's a quality write-up and contains a one-line PoC exploit and full exploits written Bash, Python and Ruby, as well as instructions on how to implement a fix until a more complete patch is released.
New patches have been made available on Monday, for versions 5.6.2, 5.6.1 and 5.6.0 of vBulletin Connect, and they disable the PHP Module widget.
"All older versions should be considered vulnerable. Sites running older versions of vBulletin need to be upgraded to vBulletin 5.6.2 as soon as possible," they advised, and noted that vBulletin Cloud sites are not affected by this issue.
vBulletin flaws, especially when they allow remote code execution without authentication, are usually speedily leveraged by attackers, so admins are advised to implement the patches ASAP..
