1DescriptionCVE.org
A vulnerability was determined in dromara lamp-cloud up to 5.10.0. This issue affects some unknown processing of the file FileChunkController.java of the component chunk-check endpoint. Executing a manipulation of the argument Name can lead to path traversal. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Path traversal in dromara lamp-cloud (versions up to 5.10.0) exposes the chunk-check endpoint of FileChunkController.java to remote directory traversal via a crafted 'Name' argument, potentially allowing attackers to read or write files outside the intended upload directory. No authentication is required per the CVSS 4.0 vector (PR:N), and a public exploit has been disclosed (CVSS E:P modifier), lowering the barrier for opportunistic exploitation. …

Vulnerability AssessmentAI
| Exploitation | The chunk-check endpoint served by FileChunkController.java must be reachable over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.5 (Medium) with vector AV:N/AC:L/AT:N/PR:N/UI:N reflects a remotely exploitable, low-complexity flaw requiring no authentication - a meaningful threat posture. … 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 has not responded to the responsible disclosure filed via GitHub issue #413 (https://github.com/dromara/lamp-cloud/issues/413). … Detailed patch versions, workarounds, and compensating controls in full report. |
