CVE-2016-15045: Deepin lastore-daemon Privilege Escalation via Unsigned .deb Installation

• Severity: high (CVSS 8.5 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-07-23 · updated 2026-06-17
• Weakness: CWE-269

Description

A local privilege escalation vulnerability exists in lastore-daemon, the system package manager daemon used in Deepin Linux (developed by Wuhan Deepin Technology Co., Ltd.). In versions 0.9.53-1 (Deepin 15.5) and 0.9.66-1 (Deepin 15.7), the D-Bus configuration permits any user in the sudo group to invoke the InstallPackage method without password authentication. By default, the first user created on Deepin is in the sudo group. An attacker with shell access can craft a .deb package containing a malicious post-install script and use dbus-send to install it via lastore-daemon, resulting in arbitrary code execution as root.

Affected products

• Wuhan Deepin Technology Co., Ltd. Deepin Linux: 0.9.53-1 (Deepin 15.5), 0.9.66-1 (Deepin 15.7)
