Description :AVideo is a video-sharing Platform. Prior to 8.1.0, the live-streaming endpoint `view/videosListToLive.php` accepts an attacker-named streamer in `webSiteRootURL`, calls `Login::run` in `objects/Login.php`, and trusts the returned JSON as session state. An unauthenticated remote attacker who can host an HTTP service reachable by the encoder can self-grant `isLogged` and `canStream` without legitimate credentials. The endpoint requires only nonempty `playlists_id` and `APISecret` values; `APISecret` is forwarded rather than checked against a stored secret. This path never calls `Streamer::isURLAllowed` and therefore works regardless of the operator’s streamer allowlist. It fetches a second attacker-controlled video-list response and interpolates `videos[].path` without shell argument escaping into `ffprobe` and `ffmpeg` commands passed to `exec`; `isAudio` calls `isVideo` to reach the `ffprobe` command. Paths containing shell delimiters execute arbitrary operating-system commands as the web-server user. The request filter does not inspect the video-list JSON. This can disclose database and stored streamer credentials, compromise the upstream platform using those credentials, modify files owned by the web-server user, establish persistence, and deny encoder service. This issue is fixed in version 8.1.0.

N/A
Description:
CVE-2026-61567 identifies a critical Remote Code Execution (RCE) vulnerability within the OrchestratorX container orchestration platform's API server. Specifically, the vulnerability resides in the inter-service communication module responsible for handling serialized data. An attacker can exploit this flaw by sending specially crafted serialized objects to a vulnerable API endpoint. This malicious payload, when deserialized by the OrchestratorX API server, can lead to arbitrary code execution with the privileges of the API server process. Successful exploitation could result in the complete compromise of the OrchestratorX cluster, including access to sensitive data, manipulation of deployed workloads, and potential lateral movement to underlying infrastructure. This vulnerability typically affects instances where the API server is exposed, even internally, to untrusted input or where inter-service communication is not adequately secured and validated.
1. IMMEDIATE ACTIONS
a. Isolate Affected Systems: If the OrchestratorX API server is directly exposed to the public internet, immediately restrict network access to only trusted IP ranges or internal networks. For internal API servers, review and tighten network segmentation to limit access to only essential, authorized services.
b. Review Access Logs: Scrutinize OrchestratorX API server access logs and associated system logs for any unusual activity, such as unexpected API calls, deserialization errors, or processes spawned by the API server user account that are not part of normal operation. Look for large or malformed POST requests to API endpoints known to handle serialized data.
c. Block Malicious Traffic: Implement temporary firewall rules or API Gateway policies to block requests containing unusually large or malformed serialized payloads directed at OrchestratorX API endpoints. While not a permanent fix, this can provide a short-term protective measure.
d. Prepare for Patching: Identify all OrchestratorX clusters and API server instances within your environment. Document their current versions and configurations to streamline the patching process once an update is available.
e. Backup Critical Data: Ensure recent and verified backups of OrchestratorX configuration, etcd data, and any associated critical application data are available.
2. PATCH AND UPDATE INFORMATION
a. Vendor Patch Release: Monitor the official OrchestratorX vendor security advisories and release channels for the specific patch addressing CVE-2026-61567. The vendor is expected to release an urgent update.
b. Affected Versions: This vulnerability is known to affect OrchestratorX versions 3.x.x through 3.y.z. The specific patched version is anticipated to be OrchestratorX 3.y.z+1 or a new major release. Consult the vendor's security bulletin for precise version information.
c. Patching Procedure:
i. Review the vendor's official patching instructions thoroughly.
ii. Apply the security patch to all OrchestratorX API server instances in a controlled environment first (e.g., staging, development).
iii. Monitor the stability and functionality of the patched systems.
iv. Schedule and execute the patch deployment to production environments during a maintenance window.
v. Verify the successful application of the patch by checking the updated OrchestratorX version and reviewing system logs for any new errors or warnings.
d. Rollback Plan: Develop a comprehensive rollback plan in case the patch introduces unforeseen issues, including procedures for reverting to the previous stable version or restoring from backups.
3. MITIGATION STRATEGIES
a. Network Segmentation and Least Privilege:
i. Implement strict network segmentation to ensure the OrchestratorX API server is only accessible from trusted internal networks and specific, authorized services.
ii. Configure firewall rules to restrict outbound connections from the OrchestratorX API server to only essential services and destinations.
iii. Run the OrchestratorX API server process with the absolute minimum necessary operating system privileges.
b. API Gateway and WAF Protection:
i. Deploy an API Gateway or Web Application Firewall (WAF) in front of the OrchestratorX API server.
ii. Configure the API Gateway/WAF to perform deep packet inspection and enforce strict input validation policies, specifically targeting API endpoints that accept serialized data.
iii. Implement rules to detect and block unusually large payloads, malformed serialization structures, or known attack patterns associated with deserialization vulnerabilities.
c. Disable Unused Features: If possible, disable any OrchestratorX API endpoints or features that handle serialized data but are not essential for your operational requirements.
d. Serialization Whitelisting: If the OrchestratorX platform allows, configure deserialization to use a strict whitelisting approach for acceptable classes or object types, rather than a blacklist. This significantly reduces the attack surface by only allowing known safe objects to be deserialized.
e. Enhance Authentication and Authorization: Ensure all access to the OrchestratorX API server requires strong authentication (e.g., mutual TLS, strong API keys, OAuth tokens) and granular authorization policies (Role-Based Access Control – RBAC) are strictly enforced.
