DescriptionCVE.org

A path validation weakness in archive extraction/write handling allows entries with traversal sequences to be written outside the intended build artifacts location.

AnalysisAI

Authenticated low-privilege users of JFrog Artifactory can write arbitrary files outside the intended build artifacts location via a path traversal flaw in archive extraction. The vulnerability allows an attacker who has already obtained limited access to the application to overwrite critical files, potentially escalating to remote code execution. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Authenticate to Artifactory with low-privilege credentials
Delivery
Craft an archive containing entries with path traversal filenames
Exploit
Upload the malicious archive via the artifact upload functionality
Execution
Artifactory extracts archive without proper path sanitization
Persist
Arbitrary file written outside the intended directory
Impact
Achieve remote code execution or system compromise

Vulnerability AssessmentAI

Exploitation The attacker must possess valid low-privilege credentials for the JFrog Artifactory application (PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment CVSS 3.1 vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H indicates a remote, low-complexity attack requiring low privileges and no user interaction, resulting in full confidentiality, integrity, and availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with low-privilege credentials to an Artifactory instance uploads a crafted archive containing files with path traversal sequences (e.g., ../../bin/evil.dll). When the server extracts the archive to the build artifacts directory, the malicious entry is written to an arbitrary location, overwriting a system binary or configuration file, leading to remote code execution.
Remediation Upgrade to a patched version of JFrog Artifactory as detailed in the vendor's security advisory. … Detailed patch versions, workarounds, and compensating controls in full report.
