Vulnerability Details
The vulnerability is classified under CWE-502, which pertains to deserialization issues. The specific versions affected include Trimble Cityworks prior to 15.8.9 and Cityworks with office companion versions prior to 23.10. The vulnerability's high CVSS score indicates significant potential for impact, given that it allows for remote code execution.
The attack vector is network-based, requiring high privileges for exploitation, making it critical for organizations to address this vulnerability in their security protocols.
Technical Analysis
The root cause of this vulnerability lies in improper handling of serialized data. Attackers may leverage this weakness to gain control over systems running the affected software. The attack complexity is assessed as low, meaning that exploitation could be achieved with minimal effort by an authenticated user.
Privileges required for exploitation are high, as the attacker must be authenticated. User interaction is not necessary, which further elevates the risk. The impacts on confidentiality, integrity, and availability are all rated high, underscoring the potential severity of a successful exploit.
Risk & Impact Analysis
Real-world deployment risks associated with this vulnerability are substantial. Organizations that utilize Trimble Cityworks, especially in sectors like public services and urban management, must recognize the potential for significant operational disruption and data loss. The blast radius is considerable, as an exploitation could affect entire web services reliant on the vulnerable software.
Given the high CVSS score and the existence of known exploits, organizations should address this vulnerability in their priority patch cycle. The urgency is reinforced by the high percentile of the EPSS score, indicating a strong likelihood of exploitation in the wild.
