CVE-2016-10031

Exp

WampServer 3.0.6 installs two services called 'wampapache' and 'wampmysqld' with weak file permissions, running with SYSTEM privileges. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. To properly exploit this vulnerability, the local attacker must insert an executable file called mysqld.exe or httpd.exe and replace the original files. The next time the service starts, the malicious file will get executed as SYSTEM. NOTE: the vendor disputes the relevance of this report, taking the position that a configuration in which "'someone' (an attacker) is able to replace files on a PC" is not "the fault of WampServer.

Base score Version Severity Vector Exploitability Impact Score source
7.5 3.0 HIGH
CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
