DescriptionCVE.org

An OS command injection vulnerability in the media archiving and export pipeline component of kanishka-linux Reminiscence v0.3.0 allows attackers to execute arbitrary commands via supplying a crafted input.

AnalysisAI

Remote code execution in kanishka-linux Reminiscence v0.3.0 allows unauthenticated attackers to execute arbitrary OS commands by supplying crafted input to the media archiving and export pipeline component. The CVSS 9.8 rating reflects network-reachable, unauthenticated exploitation with full impact to confidentiality, integrity, and availability, though no public exploit identified at time of analysis and EPSS sits at 0.67% (47th percentile) indicating limited observed exploitation pressure so far.

Vulnerability AssessmentAI

Exploitation The attacker needs network reachability to a running Reminiscence v0.3.0 instance and the ability to submit input into the media archiving or export pipeline component - in practice, access to whatever endpoint accepts a URL or target identifier for archiving/exporting. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H) describes a textbook critical-severity remote, unauthenticated code-execution bug, and the SSVC-style read is: exploitation status = none reported, automatable = likely yes (single crafted request), technical impact = total. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who can reach the Reminiscence web interface submits a URL or export-target value crafted with shell metacharacters (e.g., a URL containing backticks or '; <cmd>') to the archiving or export pipeline endpoint; the server-side handler passes this through to a shell-invoked downloader or converter, executing the attacker's command as the Reminiscence service user. From there the attacker can drop a webshell, exfiltrate the archive database, or pivot to the host. …
Remediation No vendor-released patch identified at time of analysis - there is no upstream fix version listed in the input data, only a third-party gist and the NVD record. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all systems running Reminiscence v0.3.0 and isolate or restrict network access to the media archiving and export pipeline component. …
