Overview
A Cross-Site Request Forgery (CSRF) vulnerability, identified as CVE-2025-62687, has been discovered in LogStare Collector. This vulnerability allows an attacker to potentially execute unintended actions on behalf of a logged-in user, simply by tricking them into visiting a malicious webpage. This article provides a detailed overview of the vulnerability, its potential impact, and the necessary steps to mitigate the risk.
Technical Details
CVE-2025-62687 exists because LogStare Collector does not properly validate the origin of requests, making it susceptible to CSRF attacks. An attacker can craft a malicious HTML page containing a request that, when visited by an authenticated LogStare Collector user, will be automatically sent to the LogStare Collector server. This request will appear to originate from the user, leading the server to execute the attacker’s intended action (e.g., changing settings, adding users, etc.) provided the user has the necessary privileges.
For example, a malicious page might contain the following HTML (illustrative):
<form action="https://your-logstare-collector-instance/admin/change_password" method="POST">
<input type="hidden" name="new_password" value="attacker_password">
<input type="hidden" name="confirm_password" value="attacker_password">
<input type="submit" value="Click here for a free prize!">
</form>
<script>
document.forms[0].submit(); // Automatically submit the form
</script>
Visiting this page while logged into LogStare Collector as an administrator could potentially change the administrator’s password to “attacker_password”. Note that the actual parameters and URL would depend on the specific functionality vulnerable to CSRF.
CVSS Analysis
Currently, the Common Vulnerability Scoring System (CVSS) score for CVE-2025-62687 is listed as N/A. However, this does NOT mean the vulnerability is not important. CSRF vulnerabilities can have significant impacts, and a score will likely be assigned soon. The severity will depend on the privileges required to execute impactful actions and the ease of exploitation.
Given the nature of CSRF attacks, a low-to-medium CVSS score is anticipated if the impact is limited to low-privileged actions. However, if an attacker can leverage this vulnerability to perform administrative actions, a high CVSS score is possible.
Possible Impact
The potential impact of CVE-2025-62687 depends on the actions an attacker can trigger through a CSRF attack. Potential impacts include:
- Account Compromise: Changing user passwords.
- Configuration Changes: Modifying LogStare Collector settings, potentially disabling security features.
- Data Manipulation: Altering or deleting collected logs, impacting data integrity and compliance.
- Privilege Escalation: Adding new administrative users or granting elevated privileges to existing accounts.
The severity of the impact depends heavily on the privileges of the user being targeted.
Mitigation and Patch Steps
The primary method for mitigating CVE-2025-62687 is to apply the available patch from LogStare. Follow these steps:
- Check for Updates: Regularly check the LogStare website and update your LogStare Collector installation to the latest version.
- Apply the Patch: Download and install the patch specifically designed to address CVE-2025-62687. Refer to the LogStare documentation for detailed instructions.
- Workarounds (If No Patch Available): If a patch is not immediately available, consider implementing the following workarounds:
- Educate Users: Train users to be cautious about clicking links in emails or visiting untrusted websites.
- Browser Extensions: Install browser extensions designed to prevent CSRF attacks (e.g., Anti-CSRF Origin Check). However, rely on these only as a temporary measure.
- Network Segmentation: Isolate the LogStare Collector instance on a secured network segment.
