CVE-2026-77644 – Authentication Bypass / Unauthorized Password Change – PTC Windchill Risk and Relia

Be the first to know when new zero-days emerge:

Summary

CVE-2026-77644 is a critical access control bypass vulnerability in PTC Windchill Risk and Reliability (WRR) Enterprise Edition (formerly known as Relex), rated 9.3 (Critical). The flaw stems from missing authentication on a critical function combined with an unverified password change mechanism, allowing a remote, unauthenticated attacker to alter account credentials without any prior access or user interaction. Given the network attack vector and lack of required privileges, the vulnerability is well suited to automated, large-scale exploitation attempts against internet-exposed WRR instances.

Technical details

  • Root cause: The application exposes a critical function — tied to password/credential management — without enforcing authentication (CWE-306: Missing Authentication for Critical Function), and the associated password-change operation does not verify the requester’s identity or current credentials before applying the change (CWE-620: Unverified Password Change).
  • Trigger conditions: An attacker only needs network reachability to the vulnerable WRR endpoint; no valid session, credentials, or user interaction are required to invoke the affected functionality.
  • Attack vector: Network (remote), leveraging what MITRE’s CAPEC-36 classifies as use of an unpublished/undocumented interface or functionality to reach the vulnerable logic.
  • Impact: Successful exploitation allows an unauthenticated attacker to bypass access controls and change account passwords, which can lead to full account takeover and compromise of confidentiality, integrity, and availability of data managed within Windchill Risk and Reliability.

Affected software

  • PTC Windchill Risk and Reliability (WRR) Enterprise Edition (formerly Relex) — versions 11.1 through 13.1

Severity

  • CVSS v4.0 Base Score: 9.3 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/RE:M/U:Red
  • Attack Vector: Network | Attack Complexity: Low | Privileges Required: None | User Interaction: None
  • High impact to Confidentiality, Integrity, and Availability

Mitigation and recommended actions

  • Immediate: Consult and apply the fix detailed in PTC’s official advisory (Support Article CS474818) for Windchill Risk and Reliability Enterprise Edition, and upgrade any affected 11.1–13.1 deployment to the version PTC designates as remediated.
  • If a patch cannot be applied immediately:
    • Restrict network access to WRR administrative and authentication-related endpoints to trusted internal networks or VPN only — do not expose them directly to the internet.
    • Monitor authentication and password-change logs for unexpected or unauthenticated password reset activity.
    • Review existing accounts for unauthorized password changes or newly created/modified credentials since the vulnerability’s disclosure.
    • Engage PTC support/Trust Center channels for guidance specific to your deployment version and any available interim workarounds.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
