DescriptionCVE.org

Improper access control in Hashtopolis server web-interface chunk activity component for versions prior to 0.14.8 allows any created account to read all cracked hashes of a Hashtopolis server instance.

AnalysisAI

Broken object-level authorization in the Hashtopolis server web-interface chunk activity component lets any authenticated low-privilege account read all cracked hashes across the entire server, regardless of access-group membership. Affecting all versions prior to 0.14.8, the flaw exposes recovered plaintext credentials - the core sensitive output of the platform - to users who should only see their own group's data. …

Vulnerability AssessmentAI

Exploitation Requires a valid authenticated account on the target Hashtopolis server (PR:L) - the description states 'any created account' can read all cracked hashes, so the only prerequisite is possession of any account, not administrative rights. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N) scoring 7.1 is internally consistent with the description: network-reachable web interface, low attack complexity, low privileges required (any created account), no user interaction, and a pure confidentiality impact (VC:H) with no integrity or availability effect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has been granted (or has self-registered for) any account on a shared Hashtopolis instance browses to the chunk activity component and requests chunk/hash data belonging to access groups they are not a member of. Because the component does not verify group ownership, the interface returns cracked plaintext hashes from every group on the server, letting the attacker harvest credentials recovered by other teams' jobs. …
Remediation Upgrade to the vendor-released patch: Hashtopolis server v0.14.8 (https://github.com/hashtopolis/server/releases/tag/v0.14.8), which the release notes state fixes access issues where users could read chunk and hash info from access groups they were not members of. … Detailed patch versions, workarounds, and compensating controls in full report.
