CVE-2023-27465: A vulnerability has been identified in SIMOTION C240 (All versions >= V5.4 < V5.5 SP1), SIMOTION C240 PN (All versions >= V5.4 < V5.5 SP1),

Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.27% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. 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 SIMOTION C240 (All versions >= V5.4 < V5.5 SP1), SIMOTION C240 PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D410-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D410-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D425-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D425-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D435-2 DP (All versions >= V5.4 < V5.5 SP1), SIMOTION D435-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D445-2 DP/PN (All versions >= V5.4), SIMOTION D445-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION D455-2 DP/PN (All versions >= V5.4 < V5.5 SP1), SIMOTION P320-4 E (All versions >= V5.4), SIMOTION P320-4 S (All versions >= V5.4). When operated with Security Level Low the device does not protect access to certain services relevant for debugging. This could allow an unauthenticated attacker to extract confidential technology object (TO) configuration from the device.

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.

Bug bounty scope

No known public program.

Source: bounty-targets-data (public HackerOne, Bugcrowd, Intigriti, YesWeHack listings).
