Description

Codemers KLIMS 1.6.DEV allows Python code injection. A user can provide Python code as an input value for a parameter or qualifier (such as for sorting), which will get executed on the server side.

Technical Analysis

CVE-2025-43948 is a high-severity vulnerability affecting Codemers KLIMS version 1.6.DEV, where the application allows untrusted user input to be executed as Python code on the server side. Specifically, the vulnerability arises because the software accepts Python code as input parameters or qualifiers, such as those used for sorting operations, and directly executes this code without proper sanitization or validation. This constitutes a classic code injection flaw categorized under CWE-77 (Improper Neutralization of Special Elements used in a Command). The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact includes potential unauthorized code execution, which can lead to partial confidentiality, integrity, and availability loss. Although no known exploits are currently reported in the wild, the ease of exploitation and the nature of the vulnerability make it a significant threat. The lack of vendor or product-specific information limits precise identification, but the affected software is a laboratory information management system (KLIMS), which is typically used in scientific, healthcare, and industrial environments. The vulnerability was published on April 22, 2025, and no patches or mitigations have been officially released yet, increasing the urgency for organizations to implement compensating controls.

Potential Impact

For European organizations, the impact of this vulnerability can be substantial, especially for entities relying on Codemers KLIMS or similar laboratory information management systems. Successful exploitation could allow attackers to execute arbitrary Python code on the server, potentially leading to data breaches involving sensitive laboratory or research data, manipulation or destruction of critical data, and disruption of laboratory operations. This could affect pharmaceutical companies, research institutions, healthcare providers, and industrial labs, undermining data integrity and availability. Given the critical role of such systems in compliance with regulatory frameworks like GDPR and industry-specific standards, exploitation could also result in legal and financial repercussions. Furthermore, the ability to execute code remotely without authentication broadens the attack surface, increasing the risk of widespread compromise if the software is deployed in interconnected environments. The vulnerability could also be leveraged as a foothold for lateral movement within networks, escalating the threat to broader organizational IT infrastructure.

Mitigation Recommendations

Since no official patches are currently available, European organizations should take immediate steps to mitigate risk. First, restrict network access to the KLIMS server by implementing strict firewall rules and network segmentation, limiting exposure to trusted internal networks only. Second, employ application-layer filtering or web application firewalls (WAFs) configured to detect and block suspicious input patterns indicative of code injection attempts, such as embedded Python syntax in parameters. Third, conduct thorough input validation and sanitization at the application level, if possible, by disabling or restricting dynamic code execution features in the KLIMS configuration or source code. Fourth, monitor server logs and network traffic for anomalous activities, including unexpected Python code execution or unusual parameter values. Fifth, implement strict access controls and least privilege principles for users interacting with the KLIMS system to reduce the risk of insider exploitation. Finally, maintain an incident response plan tailored to address potential code injection incidents and prepare for rapid containment and recovery. Organizations should also engage with the vendor or community to obtain updates or patches as soon as they become available.
