Overview
CVE-2025-62189 is an incorrect authorization vulnerability discovered in LogStare Collector. This flaw allows a non-administrative user to create new user accounts by sending a specially crafted HTTP request. Successfully exploiting this vulnerability could lead to unauthorized access, privilege escalation, and potential compromise of the LogStare Collector system.
Technical Details
The vulnerability resides within the UserRegistration functionality of LogStare Collector. The application fails to properly validate the user’s authorization level before processing the user creation request. By crafting a malicious HTTP request containing the necessary parameters to create a new user, an attacker with a basic user account can bypass the intended authorization checks and create accounts with potentially elevated privileges. The specific parameters and endpoint involved are detailed in the LogStare advisory (see references).
CVSS Analysis
Currently, both the CVSS score and severity for CVE-2025-62189 are listed as N/A. However, given the nature of the vulnerability – allowing unauthorized user creation – a complete CVSS analysis is crucial to determine the precise risk. Based on the impact, it is likely to be classified as High or Critical once a score is assigned. A lack of proper authorization checks always carries a severe risk.
Possible Impact
The potential impact of exploiting CVE-2025-62189 is significant:
- Unauthorized Access: Attackers can create new administrative accounts, granting them full access to the LogStare Collector system.
- Privilege Escalation: Existing low-privilege accounts can be used to create new accounts with higher privileges.
- Data Breach: Compromised accounts can be used to access and exfiltrate sensitive data collected and stored by LogStare Collector.
- System Compromise: Attackers can modify system configurations, install malware, or disrupt normal operations.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-62189, it is strongly recommended to apply the patch provided by LogStare. Follow these steps:
- Apply the Patch: Download and install the latest version of LogStare Collector that addresses this vulnerability. Refer to the LogStare security advisory for detailed instructions.
- Review User Accounts: After applying the patch, review existing user accounts for any unauthorized or suspicious entries.
