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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
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 impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

1. Immediately review and reduce session expiration times in HCL BigFix IVR 4.2 to the shortest practical duration consistent with operational needs. 2. Implement forced re-authentication for sensitive operations or after periods of inactivity. 3. Monitor session activity logs for unusual patterns indicating prolonged or suspicious sessions. 4. Enforce multi-factor authentication (MFA) to reduce the risk of credential misuse. 5. If possible, apply any vendor patches or updates addressing session management issues once available. 6. Consider deploying web application firewalls (WAFs) or API gateways to detect and block anomalous API calls. 7. Educate administrators and users about secure session handling and the risks of leaving sessions active. 8. Conduct regular security audits focusing on session management controls and token invalidation mechanisms. 9. Isolate critical API endpoints behind additional authentication or network segmentation to limit exposure. 10. Engage with HCLSoftware support for guidance and to track patch releases related to this vulnerability.

Description

CVE-2025-31962 is a vulnerability in HCL BigFix IVR version 4.2 where insufficient session expiration in the Web UI authentication component allows authenticated attackers to maintain prolonged unauthorized access to protected API endpoints. The flaw arises from excessive session expiration periods, enabling attackers with valid credentials to extend their access beyond intended limits. Although the CVSS score is low (2.0), the issue could lead to confidentiality risks if attackers exploit prolonged sessions. No known exploits are reported in the wild, and the vulnerability requires high privileges and user interaction to exploit. European organizations using HCL BigFix IVR 4.2 should review session management policies and apply any available patches or compensating controls. Countries with significant HCL BigFix deployments and critical infrastructure relying on this product are more likely to be affected. Mitigations include reducing session timeout durations, enforcing re-authentication, and monitoring session activity closely.

Impact

For European organizations, the impact of this vulnerability is primarily related to confidentiality risks due to prolonged unauthorized access. Organizations using HCL BigFix IVR 4.2 may face increased risk of data exposure or unauthorized API usage if attackers leverage extended sessions. While the vulnerability does not directly compromise system integrity or availability, it can facilitate lateral movement or data reconnaissance within the network. This is particularly concerning for sectors with sensitive data or critical infrastructure management, such as finance, energy, and government agencies. The low CVSS score suggests limited immediate risk, but the potential for session hijacking or misuse in environments with weak session controls could amplify the impact. European entities with compliance requirements around session management and access control (e.g., GDPR, NIS Directive) should consider this vulnerability a risk to their security posture and regulatory adherence.

Summary

CVE-2025-31962 identifies a security vulnerability classified under CWE-613 (Insufficient Session Expiration) in HCL BigFix IVR version 4.2. The vulnerability exists in the Web UI authentication component, where session tokens or cookies have excessively long expiration periods. This design flaw allows an authenticated attacker—who already has valid credentials—to maintain access to protected API endpoints for longer than intended, effectively prolonging their session beyond secure limits. The vulnerability does not directly allow privilege escalation or remote unauthenticated access but poses a risk by extending the window during which an attacker can operate undetected. The CVSS v3.1 score is 2.0, reflecting low severity due to the requirement of high privileges (PR:H) and user interaction (UI:R), as well as the limited impact on confidentiality (C:L) and no impact on integrity or availability. No known exploits have been reported in the wild, and no patches are currently linked, indicating that organizations should proactively implement mitigations. This vulnerability highlights the importance of strict session management, especially in enterprise software managing critical endpoints. Attackers exploiting this could maintain unauthorized access if sessions are not invalidated promptly after logout or inactivity.
