Local file disclosure via undecoded WEB-INF paths
Published Mar 16, 2022 · Updated Oct 4, 2024
Path traversal in Atlassian FishEye and Crucible before 4.8.9 allows remote attackers to read local files through crafted URLs. The WEB-INF request path is checked before URL decoding, so encoded traversal sequences bypass the earlier access-control fix and resolve protected files. No authentication or user interaction is required, but disclosure is limited to files readable by the service process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <4.8.9
- Affected versionversion=unspecified <4.8.9
