CVE-2025-60035
Published: 18 February 2026
Description
A vulnerability has been identified in the OPC.Testclient utility, which is included in Rexroth IndraWorks. All versions prior to 15V24 are affected. This flaw allows an attacker to execute arbitrary code on the user's system by parsing a manipulated file…

containing malicious serialized data. Exploitation requires user interaction, specifically opening a specially crafted file, which then causes the application to deserialize the malicious data, enabling Remote Code Execution (RCE). This can lead to a complete compromise of the system running the OPC.Testclient.
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the deserialization vulnerability by identifying, reporting, and correcting the flaw through timely application of vendor patches for versions prior to 15V24.
Validates manipulated file inputs containing serialized data before deserialization to ensure they are well-formed and free of malicious content.
Implements memory safeguards like DEP and ASLR to protect against arbitrary code execution resulting from successful deserialization of malicious data.
Security SummaryAI
CVE-2025-60035 is a deserialization vulnerability (CWE-502) in the OPC.Testclient utility, which is included in Rexroth IndraWorks. All versions prior to 15V24 are affected. The flaw enables arbitrary code execution when the application parses a manipulated file containing malicious serialized data.
Exploitation requires local access (AV:L) with low complexity (AC:L) and no privileges (PR:N), but user interaction (UI:R) is necessary—the victim must open a specially crafted file in OPC.Testclient, triggering deserialization of the malicious data. This leads to remote code execution (RCE) with high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), potentially resulting in complete compromise of the system running the utility. The CVSS v3.1 base score is 7.8.
