Lifecycle Timeline
4DescriptionCVE.org
A vulnerability was detected in stilleshan ServerStatus 1.0/2.0. Impacted is an unknown function of the file server/src/main.cpp of the component Stats Generation. Performing a manipulation of the argument custom results in cross site scripting. It is possible to initiate the attack remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stored cross-site scripting in stilleshan ServerStatus 1.0 and 2.0 allows a remote authenticated attacker to inject malicious JavaScript via the custom argument processed in the Stats Generation component (server/src/main.cpp). When an administrator or other user subsequently views the affected stats page, the stored payload executes in their browser session, enabling session hijacking or credential theft. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) a valid low-privilege authenticated account on the target ServerStatus instance - unauthenticated remote exploitation is not possible per the PR:L CVSS 4.0 metric; (2) the instance must be running stilleshan ServerStatus version 1.0 or 2.0; (3) a victim user, typically an administrator, must view the affected stats page after injection (UI:P passive interaction). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 2.0 accurately reflects the constrained attack profile: exploitation requires a valid low-privilege authenticated session (PR:L) and passive victim interaction (UI:P), ruling out fully automated mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis - the vendor did not respond to coordinated disclosure, and no patched version is confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
