CVE-2023-42661Network attack vector

Remote code execution via arbitrary file write

Published Mar 7, 2024 · Updated Aug 16, 2024

Arbitrary file write in JFrog Artifactory before 7.76.2 allows remote authenticated users to write untrusted data via crafted requests. Artifact validation fails to constrain where untrusted artifact data is written, although JFrog has not disclosed the affected endpoint or code path. High-privileged authenticated access is required; successful writes can crash the service or enable remote code execution.
