CVE-2025-15244 identifies a race condition vulnerability in PHPEMS up to version 11.0, specifically in an unspecified function within the Purchase Request Handler component. A race condition occurs when multiple processes or threads access shared data concurrently, and the final outcome depends on the sequence or timing of these accesses, potentially leading to inconsistent or unintended states. This vulnerability can be triggered remotely without requiring authentication or user interaction, but the attack complexity is high, and exploitability is difficult, indicating that an attacker must carefully time or orchestrate requests to exploit the flaw. The impact primarily affects data integrity within the purchase request processing, potentially allowing attackers to manipulate purchase requests or cause inconsistent transaction states. The CVSS 4.0 base score is 6.3 (medium), reflecting network attack vector, high attack complexity, no privileges or user interaction needed, and limited integrity impact. No confidentiality or availability impacts are noted. No patches or mitigations are currently published, and no known exploits have been observed in the wild, though public disclosure increases risk of future exploitation. The vulnerability highlights the need for proper concurrency controls and input validation in multi-threaded or asynchronous components handling critical business logic such as purchase requests.

For European organizations, especially those relying on PHPEMS 11.0 for procurement and purchase management, this vulnerability poses a risk to the integrity of purchase request data. Manipulation or inconsistent processing of purchase requests could lead to financial discrepancies, procurement errors, or supply chain disruptions. While confidentiality and availability are not directly impacted, the integrity compromise could affect business operations and compliance with financial regulations. Organizations in sectors with stringent procurement controls, such as manufacturing, public sector, and critical infrastructure, may face increased operational risk. The remote exploitability without authentication raises the threat level, but the high complexity and lack of known exploits reduce immediate risk. However, the public disclosure means attackers may develop exploits over time, necessitating proactive mitigation. The vulnerability could also be leveraged as part of a broader attack chain targeting supply chain or financial systems.

1. Monitor PHPEMS vendor communications closely for official patches or updates addressing CVE-2025-15244 and apply them promptly once available. 2. Implement application-level concurrency controls and locking mechanisms in the Purchase Request Handler to prevent race conditions, such as database transaction isolation or mutexes around critical sections. 3. Conduct thorough code reviews and testing focused on multi-threaded or asynchronous processing paths in PHPEMS to identify and remediate similar race conditions. 4. Restrict network access to PHPEMS interfaces handling purchase requests using firewalls or network segmentation to limit exposure to remote attackers. 5. Employ runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block suspicious request patterns indicative of race condition exploitation attempts. 6. Enhance logging and monitoring of purchase request transactions to detect anomalies or inconsistencies that may indicate exploitation. 7. Train development and operations teams on secure coding practices related to concurrency and race conditions to prevent future vulnerabilities.
