Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Restrict access to the vulnerable SOAP endpoint '/WS/PDAWebService.asmx' by implementing network-level controls such as IP whitelisting or VPN requirements to limit exposure to trusted users only.
Implement rate limiting and anomaly detection on the web service to detect and block repeated requests that indicate user enumeration attempts.
Employ web application firewalls (WAFs) with custom rules to detect and block suspicious SOAP requests targeting the 'GetLastDatePasswordChange' action with the 'pda:username' parameter.
Monitor logs for unusual access patterns or repeated failed attempts to enumerate users and respond promptly to incidents.
Enforce strong password policies and multi-factor authentication (MFA) to reduce the risk of credential-based attacks that could follow user enumeration.
Engage with TCMAN vendor support to obtain patches or updates as they become available and plan for timely deployment.
Conduct user awareness training to recognize phishing attempts that may leverage enumerated usernames.
Consider temporarily disabling or restricting the vulnerable service if it is not essential to business operations until a patch is available.

Description

CVE-2025-41014 is a medium-severity user enumeration vulnerability in TCMAN GIM v11 (20250304). It allows unauthenticated attackers to verify the existence of users via the 'pda:username' parameter in the SOAP action 'GetLastDatePasswordChange' at the endpoint '/WS/PDAWebService.asmx'. This exposure of sensitive information (CWE-200) can facilitate further targeted attacks such as phishing or brute force. The vulnerability requires no authentication or user interaction and has a CVSS 4.0 base score of 6.9. There are no known exploits in the wild and no patches currently available. European organizations using TCMAN GIM should be aware of the risk of user enumeration leading to compromised confidentiality and should implement mitigations promptly. Countries with higher adoption of TCMAN products and critical infrastructure using this software are at greater risk.

Impact

For European organizations using TCMAN GIM, this vulnerability primarily threatens the confidentiality of user information by allowing attackers to confirm valid usernames without authentication. This can significantly aid attackers in mounting targeted phishing campaigns, credential stuffing, or brute force attacks, potentially leading to unauthorized access if combined with weak password policies or other vulnerabilities. Organizations in sectors with high-value targets, such as finance, government, or critical infrastructure, may face increased risk due to the strategic value of user enumeration data. The exposure can also undermine trust in the affected systems and lead to compliance issues under data protection regulations like GDPR, which mandates protection of personal data. While the vulnerability itself does not allow direct system compromise, it lowers the barrier for attackers to escalate attacks, increasing overall organizational risk. The lack of patches and known exploits means organizations must proactively mitigate the risk to prevent exploitation.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
