  "executiveSummary": "HCL IntelliOps Event Management (IEM) is susceptible to a Session Deletion Vulnerability stemming from improper session lifecycle management.\nThe vulnerability occurs when user sessions persist on the server side despite explicit logout actions or administrative session termination commands.\nThis failure to invalidate session tokens leads to a security state where session identifiers remain active and usable beyond their intended expiration.\nThe primary impact is the potential for session hijacking or unauthorized account access, as an attacker could leverage a previously used or intercepted session token to impersonate a legitimate user.\nThe vulnerability affects HCL IntelliOps Event Management and poses significant risk to authentication integrity, as the application fails to effectively revoke access rights.\nExploitation does not necessarily require additional privileges beyond the acquisition of a persistent session identifier, allowing an attacker to bypass standard authentication workflows.\nOrganizations relying on HCL IEM for secure environment monitoring are at risk of compromised administrative or user sessions, necessitating immediate attention to session management configurations.",
  "technicalDetails": "The core of this vulnerability lies in the improper handling of session state transitions within HCL IntelliOps Event Management (IEM).\nIn a secure authentication implementation, a logout request or an administrative session termination event must trigger a server-side invalidation routine. This typically involves destroying the session object stored in the server's session registry, clearing associated session-to-user mappings, and marking the session identifier as expired or invalid within the backend data store.\nIn the context of HCL IEM, the session management component fails to fully execute these teardown procedures. When a user initiates a logout or an administrator deletes a session, the server fails to update the session state globally. Consequently, the session token remains in a 'valid' state in the memory or persistent cache managed by the application.\nThe attack flow proceeds as follows: An attacker obtains a session token through secondary means, such as network sniffing over unencrypted channels, cross-site scripting (XSS) if present, or physical access to an unattended workstation. Even if the legitimate user attempts to terminate their session, the server-side state persists. The attacker then submits the previously known session identifier within the HTTP header or cookie during a subsequent request. Because the server does not perform an exhaustive check against the revocation list or incorrectly validates the session against the existing, non-terminated object, the attacker is granted access to the application as the original user.\nThis flaw effectively bypasses the requirement for re-authentication. Because the session token is not destroyed, there is no requirement for the attacker to provide credentials or undergo multi-factor authentication (MFA). The impact is a total compromise of the session context, allowing the attacker to interact with the application with the privileges of the victim.\nThis vulnerability is particularly critical in environments where HCL IEM is accessed via shared workstations or in scenarios where session tokens are susceptible to capture. The lack of proper server-side garbage collection for session tokens represents a failure in the application's session state machine, rendering traditional logout mechanisms ineffective at revoking authorization.\nFurther post-exploitation behavior may include unauthorized configuration changes, data exfiltration, or the manipulation of event management dashboards, depending on the role and privileges associated with the hijacked session."
