Lifecycle Timeline
3DescriptionCVE.org
A vulnerability has been found in PackageKit up to 1.3.5. Affected is the function g_file_test of the file src/pk-transaction.c of the component API. Such manipulation of the argument frontend-socket leads to improper authorization. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
Improper authorization in PackageKit up to 1.3.5 allows a low-privileged authenticated remote attacker to bypass access controls via manipulation of the frontend-socket argument in the g_file_test function within pk-transaction.c, resulting in unauthorized confidentiality exposure (C:L). The vulnerability is tagged as an authentication bypass and publicly available exploit code exists, disclosed via GitHub issue #969 against the PackageKit project. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires low-privilege authenticated access to the PackageKit API (confirmed by CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N yields a base score of 4.3, reflecting a medium-low severity: network-reachable, low complexity, requires low-privilege authentication, no user interaction, no integrity or availability impact, and limited confidentiality exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a low-privileged account on a system or network segment with access to the PackageKit D-Bus API submits a crafted transaction request with a manipulated frontend-socket argument. The g_file_test authorization check in pk-transaction.c fails to correctly reject the request, allowing the attacker to read confidential package state information they would not ordinarily be authorized to access. … |
| Remediation | No vendor-released patched version was identified at time of analysis; the upstream fix status should be tracked via the GitHub issue at https://github.com/PackageKit/PackageKit/issues/969, which serves as the primary POC and potential fix discussion thread. … Detailed patch versions, workarounds, and compensating controls in full report. |
