Summary
Endress+Hauser: sudo vulnerability affects Endress+Hauser MCS200HW
Severity
Critical
Notes
Summary: The display unit of the Endress+Hauser MCS200HW is affected by a sudo chroot vulnerability.
Impact: If exploited, this vulnerability could potentially allow an unauthenticated attacker to compromise the availability, integrity, and confidentiality of the Endress+Hauser MCS200HW.
Mitigation: As a temporary mitigation measure, both system and network access to the affected functionality should be strictly restricted. Access should be limited to authorized personnel only, and exposure to external or untrusted networks should be minimized or fully blocked until an update of the display firmware has been completed.
Remediation: Endress+Hauser has released updated firmware versions that address this vulnerability. The display unit's firmware versions below 4.3.4 are affected. To address the vulnerability, customers are strongly recommended to update the display unit of their devices to firmware version 4.3.4. Endress+Hauser will include this firmware version in the MCS200HW products starting with version 1.11.5.6R. Alternatively, customers can contact Endress+Hauser directly to obtain the updated display firmware, or download the original firmware - including update instructions - from the Phoenix Contact website referenced below. Customers are strongly advised to upgrade to the latest fixed version. For assistance, please contact your local Endress+Hauser service center.
General Recommendation: Endress+Hauser recommends operating these solutions in a secure environment and restricting access to components to authorized personnel only.
CVE-2025-32463

Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option.

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.

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.

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.
