SSRF in OCS Inventory Server via Parameter Injection

Publication date: 2026-09-03

Last updated on: 2026-09-03

Assigner: Spanish National Cybersecurity Institute, S.A. (INCIBE)

Description
Server-Side Request Forgery (SSRF) vulnerability in the /ocsreports/?function=tele_activate endpoint due to insufficient validation of the HTTPS_SERV and FILE_SERV parameters. An authenticated user with operator privileges can provide arbitrary values for these parameters, causing the OCS Inventory server to make HTTP/HTTPS requests to external systems or internal resources, which could allow access to internal network services or metadata resources of cloud services.

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in the OCS Inventory server. It affects the /ocsreports/?function=tele_activate endpoint due to weak validation of the HTTPS_SERV and FILE_SERV parameters. An authenticated user with operator privileges can manipulate these parameters to make the server send HTTP/HTTPS requests to external or internal systems.

Detection Guidance

Detect this vulnerability by monitoring network traffic for unexpected outbound HTTP/HTTPS requests from the OCS Inventory server, particularly to internal or external systems. Check server logs for unusual activity involving the /ocsreports/?function=tele_activate endpoint and parameters HTTPS_SERV or FILE_SERV. Use tools like tcpdump or Wireshark to capture and analyze traffic from the server.

Impact Analysis

An attacker could exploit this to access internal network services or cloud metadata resources. This may lead to unauthorized data exposure, internal service probing, or further network compromise depending on the server's environment and configuration.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements under GDPR and HIPAA. Organizations may face compliance violations, data breach notifications, and potential penalties if exploited.

Mitigation Strategies

Immediately restrict access to the /ocsreports/?function=tele_activate endpoint to only necessary users. Validate and sanitize all input for HTTPS_SERV and FILE_SERV parameters to prevent SSRF. Update OCS Inventory to the latest patched version if available. Monitor network traffic for suspicious outbound requests.
