Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly requires validating user inputs at entry points to prevent injection of executable code enabling XSS, SQL injection, and command injection.
Mandates output filtering to mitigate XSS attacks arising from unvalidated inputs reflected in responses.
Ensures timely remediation of the specific improper input validation flaw documented in this CVE.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper input validation directly enables remote code/command injection (XSS/SQL/command) in a network-exposed app, mapping to public app exploitation and command interpreter execution.
NVD Description
HCL Aftermarket DPC is affected by Improper Input Validation which allows an attacker to inject executable code and can carry out attacks such as XSS, SQL Injection, Command Injection etc.
Deeper analysisAI
CVE-2025-55270 is an Improper Input Validation vulnerability (CWE-20) affecting HCL Aftermarket DPC software. Published on 2026-03-26 with a CVSS v3.1 base score of 3.5 (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N), it enables attackers to inject executable code through inadequate validation of user inputs, potentially facilitating attacks such as cross-site scripting (XSS), SQL injection, and command injection.
Exploitation is feasible over the network with low complexity by an authenticated attacker possessing low privileges, though it requires user interaction to succeed. The impact is limited to low confidentiality disclosure, allowing potential access to sensitive data without affecting integrity or availability.
