Description
SOEM version 2.0.0 and earlier contains multiple vulnerabilities in frame processing where a malicious device can cause the master to read data outside allocated buffers. The software uses length and offset values from device messages without validating them against buffer sizes. This can cause the master to access invalid memory locations, potentially disclosing sensitive information or causing crashes.

Score: 7.1 High
EPSS: n/a
KEV: No
Impact: Memory disclosure or crash from out‑of‑bounds reads
Action: Apply Patch
AI Analysis

Impact

Multiple out‑of‑bounds read vulnerabilities exist in the frame processing of RT‑Labs AB SOEM version 2.0.0 and earlier. The software accepts length and offset values from device messages without validating them against buffer sizes, allowing a malicious device to read data outside allocated buffers. This can expose sensitive information or lead to application crashes, and is represented by CWE‑125, CWE‑129, CWE‑191, and CWE‑787 weaknesses.

Affected Systems

The affected product is RT‑Labs AB SOEM. All installations of version 2.0.0 or earlier are impacted. No other versions are listed as vulnerable.

Risk and Exploitability

The CVSS score of 7.1 indicates a high severity risk. The EPSS score is unavailable, and the vulnerability is not listed in KEV. The likely attack vector involves a device that can send crafted messages to the SOEM master, implying a trusted device or local network attacker. An attacker could exploit the flaw to read arbitrary memory and potentially crash the master or dump sensitive data, but no exploitation evidence is currently documented.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade to a SOEM version that includes the out‑of‑bounds read fix; if a newer version is unavailable, contact RT‑Labs AB for a patch or mitigation advisory.
  • If upgrading is not possible, isolate the SOEM master from untrusted devices or networks to prevent malicious frame transmission.
  • Enable logging of received frame lengths and offsets, and monitor for abnormal high values or crashes that may indicate exploitation attempts.
