Phoenix Contact: Improper Input Validation Vulnerabilities in PLCnext Firmware
Severity
Critical
Notes
General Recommendation: Phoenix Contact recommends operating network-capable devices in closed networks or protected with a suitable firewall. For detailed information on our recommendations for measures to protect network-capable devices, please refer to our [Application note](https://dam-mdc.phoenixcontact.com/asset/156443151564/0a870ae433c19148b80bd760f3a1c1f2/107913_en_03.pdf).
Impact: The reported vulnerabilities allow an unauthenticated remote attacker to cause a denial-of-service condition, trigger unexpected behaviour through a buffer overflow, or execute unauthorized SQL queries against affected PLCnext devices. Successful exploitation could impact the availability, integrity, and confidentiality of the system.
Remediation: Phoenix Contact recommends updating affected devices to PLCnext firmware version 2026.0.3 or later, which addresses all vulnerabilities described in this advisory.
Summary: This advisory addresses multiple security vulnerabilities in PLCnext firmware versions prior to 2026.0.3. The vulnerabilities may allow unauthenticated attackers to cause denial of service, trigger unexpected system behavior, or execute unauthorized SQL queries. Successful exploitation could impact the availability, integrity, and confidentiality of affected PLCnext Control devices. All issues are resolved in PLCnext firmware version 2026.0.3.
The device's PROFINET service is affected by a buffer overflow vulnerability that exists in the default configuration. An unauthenticated remote attacker could exploit this vulnerability to reboot the device or execute arbitrary code.
9.8 (Critical)
Vendor Fix
Update to PLCnext firmware version 2026.0.3 or later which fixes this vulnerability. Check regularly for firmware updates and apply them as soon as they are available for the specific device.

An unauthenticated denial-of-service vulnerability in the device's PLCnext Engineer communication interface allows an remote attacker to interrupt access via the client application. Successful exploitation prevents communication until the PLCnext service is manually restarted.
7.5 (High)
Vendor Fix
Update to PLCnext firmware version 2026.0.3 or later which fixes this vulnerability. Check regularly for firmware updates and apply them as soon as they are available for the specific device.

An authenticated attacker with low privileges can access an endpoint in the controller’s web interface that is vulnerable to SQL injection. The vulnerability affects a SQLite database used only for storing notification messages. Therefore, the impact is limited to the system’s notification functionality.
4.3 (Medium)
Vendor Fix
Update to PLCnext firmware version 2026.0.3 or later which fixes this vulnerability. Check regularly for firmware updates and apply them as soon as they are available for the specific device.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
