CVE-2019-10918· NVD / CVE Program· CNA siemens

A vulnerability has been identified in SIMATIC PCS 7 V8.0 and earlier (All versions), SIMATIC PCS 7 V8.1 (All versions < V8.1 with WinCC V7.

Noroxi assessment

Priority: Monitor (action score 36/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 79.8% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

A vulnerability has been identified in SIMATIC PCS 7 V8.0 and earlier (All versions), SIMATIC PCS 7 V8.1 (All versions < V8.1 with WinCC V7.3 Upd 19), SIMATIC PCS 7 V8.2 (All versions < V8.2 SP1 with WinCC V7.4 SP1 Upd11), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP2 with WinCC V7.4 SP1 Upd11), SIMATIC WinCC (TIA Portal) V13 (All versions), SIMATIC WinCC (TIA Portal) V14 (All versions < V14 SP1 Upd 9), SIMATIC WinCC (TIA Portal) V15 (All versions < V15.1 Upd 3), SIMATIC WinCC Runtime Professional V13 (All versions), SIMATIC WinCC Runtime Professional V14 (All versions < V14.1 Upd 8), SIMATIC WinCC Runtime Professional V15 (All versions < V15.1 Upd 3), SIMATIC WinCC V7.2 and earlier (All versions), SIMATIC WinCC V7.3 (All versions < V7.3 Upd 19), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Upd 11), SIMATIC WinCC V7.5 (All versions < V7.5 Upd 3). An authenticatd attacker with network access to the DCOM interface could execute arbitrary commands with SYSTEM privileges. The vulnerability could be exploited by an attacker with network access to the affected system. Successful exploitation requires authentication with a low-privileged user account and no user interaction. An attacker could use the vulnerability to compromise confidentiality and integrity and availability of the affected system. At the time of advisory publication no public exploitation of this security vulnerability was known.

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
