Date: Wed, 18 Jul 2018 08:30:07 +0100 From: Alexey Sokolov <alexey+znc@...kolov.org> To: oss-security@...ts.openwall.com Subject: CVE-2018-14055: privilege escalation in ZNC Severity: high Versions affected: 1.6.0 through 1.7.0 Potentially, all earlier versions too, but there is no known way to trigger this before 1.6.0 Mitigation: upgrade to 1.7.1 Description: ZNC before 1.7.1-rc1 does not properly validate untrusted lines coming from the network, allowing a non-admin user to escalate privilege, inject rogue values into znc.conf, and gain shell access. Upstream patches: https://github.com/znc/znc/commit/a7bfbd93812950b7444841431e8e297e62cb524e https://github.com/znc/znc/commit/d22fef8620cdd87490754f607e7153979731c69d Reported by: Jeriko One <jeriko.one@....us> -- Best regards, Alexey "DarthGandalf" Sokolov
