CVE-2025-62687: Secuavail Logstare Collector CSRF Flaw

CVE-2025-62687 Overview

CVE-2025-62687 is a Cross-Site Request Forgery (CSRF) vulnerability affecting LogStare Collector, a log collection product from Secuavail. An attacker who convinces an authenticated user to view a crafted page can trigger unintended state-changing operations against the Collector under that user's session. The flaw is categorized under CWE-352: Cross-Site Request Forgery and requires user interaction to succeed.

Critical Impact
Successful exploitation lets a remote attacker perform privileged actions on LogStare Collector by leveraging an authenticated administrator's active session, undermining the integrity of the log collection infrastructure.

Technical Details for CVE-2025-62687

Vulnerability Analysis

CVE-2025-62687 is a classic web-application CSRF flaw [CWE-352] in the LogStare Collector management interface. State-changing HTTP requests are accepted without a verifiable anti-CSRF token or equivalent origin validation. As a result, the browser of an authenticated user automatically attaches session cookies to any request initiated by an attacker-controlled page.

The attack requires a logged-in user to load a crafted page while their LogStare Collector session is active. The forged request executes in the user's authenticated context and can invoke administrative endpoints. The scope of impact aligns with the actions the victim's account is permitted to perform, including configuration changes to the log collector.

Because LogStare Collector aggregates log data from monitored systems, tampering with its configuration can degrade downstream detection and incident response. The vulnerability does not directly expose data confidentiality, but it enables integrity impact on the Collector.

Root Cause

The root cause is the absence of adequate CSRF protections on authenticated endpoints. The application does not validate a synchronizer token, SameSite cookie enforcement, or Origin/Referer headers before executing state-changing operations.

Attack Vector

Exploitation requires network access to induce a victim to visit attacker-controlled content, plus an active authenticated session in LogStare Collector. The attacker hosts a page containing an auto-submitting form or JavaScript-driven fetch request targeting a Collector endpoint. When the victim loads it, the browser issues the forged request with the victim's session cookies attached.

No exploit code is publicly available at the time of writing, and the issue is not listed in the CISA Known Exploited Vulnerabilities catalog. For technical details, refer to the JVN Vulnerability Report.

Detection Methods for CVE-2025-62687

Indicators of Compromise

Unexpected configuration changes in LogStare Collector that do not correlate with authorized administrator activity.
Web server access logs showing state-changing POST requests to Collector endpoints with Referer or Origin headers pointing to untrusted external domains.
Administrative actions recorded in Collector audit logs immediately after a user visited an external URL.

Detection Strategies

Review LogStare Collector application and access logs for state-changing requests lacking a valid same-origin Referer header.
Correlate browser proxy or endpoint telemetry against Collector administrative endpoints to identify requests initiated by unrelated web pages.
Alert on administrative configuration changes performed outside of maintenance windows or from unusual user-agents.

Monitoring Recommendations

Forward LogStare Collector audit and web access logs to a centralized analytics platform for correlation with user browsing telemetry.
Monitor authenticated session activity for administrator accounts and flag concurrent access from disparate origins.
Track outbound HTTP requests from administrator endpoints to identify visits to suspicious pages preceding Collector configuration changes.

How to Mitigate CVE-2025-62687

Immediate Actions Required

Apply the vendor update referenced in the Logstare Vulnerability Advisory as soon as it is available for your deployment.
Restrict access to the LogStare Collector management interface to trusted administrative networks only.
Instruct administrators to log out of LogStare Collector when the console is not in active use and to avoid browsing untrusted sites from administrative workstations.

Patch Information

Secuavail has published guidance and fix information in the Logstare Vulnerability Advisory 2025-001. Administrators should upgrade to the fixed release identified by the vendor. Additional coordinated disclosure details are available in the JVN Vulnerability Report JVN77560819.

Workarounds

Use a dedicated browser or browser profile exclusively for LogStare Collector administration to prevent cross-origin request abuse.
Enforce network-level access controls, such as VPN or IP allow-listing, so that the Collector management endpoints are unreachable from general-purpose browsing sessions.
Configure browsers or reverse proxies to enforce strict SameSite=Strict cookie behavior and block third-party requests to the Collector where feasible.

bash

# Example reverse-proxy hardening (nginx) to restrict Collector admin access
location /collector/ {
    allow 10.0.0.0/24;      # administrative subnet
    deny  all;
    proxy_set_header Referer $http_referer;
    proxy_pass http://logstare_collector_backend;
