What is CVE-2016-15045?

A local privilege escalation vulnerability exists in lastore-daemon, the package manager daemon for Deepin Linux, allowing any user in the sudo group to execute the InstallPackage method without needing password authentication. This flaw occurs in versions 0.9.53-1 and 0.9.66-1, where the default D-Bus configuration can be exploited by an attacker with shell access. They can craft a malicious .deb package containing a harmful post-install script and use dbus-send to install it, leading to arbitrary code execution with root privileges.

Affected Version(s)

Deepin Linux 0.9.53-1 (Deepin 15.5)

Deepin Linux 0.9.66-1 (Deepin 15.7)

Exploit Proof of Concept (PoC)
