Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly limits concurrent sessions per user or account type, preventing exploitation of admin session concurrency vulnerabilities.
Ensures authenticity of communications sessions, mitigating hijacking or impersonation via session manipulation.
Enforces session termination after inactivity or specific conditions, reducing the window for concurrent session exploits.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Session concurrency flaw directly enables admin impersonation/hijacking via shared session state manipulation.
NVD Description
HCL Aftermarket DPC is affected by Admin Session Concurrency vulnerability using which an attacker can exploit concurrent sessions to hijack or impersonate an admin user.
Deeper analysisAI
CVE-2025-55275 is an Admin Session Concurrency vulnerability affecting HCL Aftermarket DPC. This flaw allows an attacker to exploit concurrent sessions, enabling them to hijack or impersonate an admin user. The vulnerability is classified under CWE-557 and has a CVSS v3.1 base score of 3.7 (AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:L), indicating low severity with primarily confidentiality impacts.
Exploitation requires network access and low privileges (such as an authenticated low-privilege user account), but demands high attack complexity and user interaction. A successful attack could allow the adversary to impersonate an administrator through session manipulation, potentially leading to limited unauthorized access to confidential information without affecting integrity or availability.
