Summary
Weidmueller: Security routers IE-SR-2TX are affected by multiple vulnerabilities
Severity
High
Notes
Summary: Weidmueller security routers IE-SR-2TX are affected by multiple vulnerabilities (CVE-2025-41661, CVE-2025-41663, CVE-2025-41683, CVE-2025-41684, CVE-2025-41687). Weidmueller has released new firmware versions of the affected products to fix the vulnerabilities. **Update Version 1.1.0:** Added CVEs CVE-2025-41683, CVE-2025-41684 and CVE-2025-41687. Updated CVSS Score for CVE-2025-41663. Removed CVE-2025-41662.
General Recommendation: As a general security measure, Weidmueller strongly recommends to change the default passwords and to minimize the network exposure of products. Limit access to trusted networks by using the appropriate mechanisms.
Impact: Weidmueller security routers are vulnerable to multiple vulnerabilities, that may lead to execution of arbitrary commands on affected devices with root privileges. Further information can be found under vulnerability details.
Remediation: Update to the new version as listed in the following table: | Product | Affected Version | Fixed Version | |----------------------------------|------------------|---------------| |IE-SR-2TX-WL | <V1.49 | V1.49 | |IE-SR-2TX-WL-4G-EU | <V1.62 | V1.62 | |IE-SR-2TX-WL-4G-US-V | <V1.62 | V1.62 |
CVE-2025-41661

An unauthenticated remote attacker can execute arbitrary commands with root privileges on affected devices due to lack of Cross-Site Request Forgery (CSRF) protection.

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
CWE-352 - Cross-Site Request Forgery (CSRF)

CVE-2025-41683

An authenticated remote attacker can execute arbitrary commands with root privileges on affected devices due to lack of improper sanitizing of user input in the Main Web Interface (endpoint event_mail_test).

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Affected products
Fixed 3 products, the same list as for CVE-2025-41661
Known affected 3 products, the same list as for CVE-2025-41661
CVE-2025-41684

An authenticated remote attacker can execute arbitrary commands with root privileges on affected devices due to lack of improper sanitizing of user input in the Main Web Interface (endpoint tls_iotgen_setting).

8.8 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Affected products
Fixed 3 products, the same list as for CVE-2025-41661
Known affected 3 products, the same list as for CVE-2025-41661
CVE-2025-41663

For u-link Management API an unauthenticated remote attacker in a man-in-the-middle position can inject arbitrary commands in responses returned by WWH servers, which are then executed with elevated privileges. To get into such a position, clients would need to use insecure proxy configurations.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CVE-2025-41687

An unauthenticated remote attacker may use a stack based buffer overflow in the u-link Management API to gain full access on the affected devices.

9.8 (Critical)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
CWE-121 - Stack-based Buffer Overflow

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.
