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

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.

Security readout for executives and security teams

Plain-English summary

CVE-2016-15045 lets a logged-in sudo-group user on affected Deepin systems abuse the package manager daemon to run code as root without a password. This is not a remote break-in by itself, but it can turn compromised or low-trust local access into full system control.

Executive priority

Treat this as high priority where Deepin is used in production, shared labs, kiosks, or developer workstations. It requires local access, but successful abuse gives root control. Legacy systems should be upgraded, isolated, or decommissioned.

Technical view

Affected Deepin lastore-daemon versions expose an unauthenticated D-Bus InstallPackage path to sudo-group users. The issue is described for 0.9.53-1 on Deepin 15.5 and 0.9.66-1 on Deepin 15.7. CVSS v4.0 is 8.5 high, mapped to CWE-269 and CWE-306.

Likely exposure

Exposure is most likely on legacy Deepin Linux 15.5 or 15.7 hosts running the listed lastore-daemon packages, especially where multiple people have shell access or default first-user sudo membership remains unchanged.

Exploitation context

Public exploit references exist, including Exploit-DB entries and a Metasploit module. The supplied sources do not show CISA KEV listing or confirmed active exploitation, so active exploitation should not be assumed.

Researcher notes

The strongest evidence covers affected versions, privilege boundary, and public exploit availability. The supplied bundle does not name a fixed version, patch commit, or official mitigation. Avoid claiming active exploitation without additional source confirmation.

Mitigation direction

  • Inventory Deepin systems and identify lastore-daemon package versions.
  • Prioritize vendor-supported updates or migration from affected Deepin releases.
  • Limit shell access to trusted administrators on affected systems.
  • Review sudo-group membership and remove unnecessary local privileges.
  • Follow Deepin or vendor guidance before changing D-Bus or package-manager policy.

Validation and detection

  • Confirm whether any hosts run Deepin 15.5 or 15.7.
  • Check installed lastore-daemon versions against 0.9.53-1 and 0.9.66-1.
  • Review sudo-group membership on exposed systems.
  • Check package-management and audit logs for unusual local package installations.
  • Track CVE and vendor sources for patch or support clarification.
