CISA Warns of Active Exploits Targeting Trimble Cityworks Software Flaw

Article Highlights

Off On

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical warning regarding an actively exploited vulnerability in Trimble Cityworks, a GIS-centric asset management software. This vulnerability, identified as CVE-2025-0994, is a deserialization of untrusted data flaw that holds a CVSS v4 score of 8.6, allowing remote code execution by authenticated users on Microsoft’s IIS web server.

The vulnerability affects all versions of Cityworks prior to 15.8.9, as well as Cityworks with office companion versions before 23.10. In response to the identified risk, Trimble released patches aimed at fixing this vulnerability on January 29, 2025.

Despite these updates, CISA has reported continuous exploitation attempts targeting specific Cityworks deployments. Investigations reveal that these exploitation attempts involve a Rust-based loader deploying Cobalt Strike and a Go-based remote access tool named VShell, along with other unidentified payloads, thus emphasizing the critical nature of the problem.

CISA has added CVE-2025-0994 to its Known Exploited Vulnerabilities catalog, underscoring the necessity for Federal Civilian Executive Branch agencies to address and remediate this flaw by February 28, 2025. Users and administrators of the affected software versions are strongly urged to apply the necessary updates without delay. Additionally, they should actively search for indicators of compromise (IoCs) to ensure their systems are not already affected.

The advisory issued by CISA highlights the imperative of keeping software updated as a primary measure to mitigate the risks associated with known vulnerabilities. This is particularly crucial for those that are actively exploited in real-world attacks, like the one currently targeting Trimble Cityworks. Cybersecurity professionals and users must adopt a vigilant stance, prioritizing the application of patches and continuous monitoring for any signs of compromise. By doing so, they can effectively protect their systems and data from the ever-evolving landscape of cyber threats. As the situation evolves, staying informed and responsive remains essential for those aiming to maintain robust cybersecurity defenses.
