AlienVault OTX Vulnerabilities

AlienVault OTX Malware

HCL Aftermarket DPC is affected by HTTP Response Splitting vulnerability where in depending on how the web application handles the split response, an attacker may be able to execute arbitrary commands or inject harmful content into the response..

CVE-2025-55271 identifies a vulnerability in HCL Aftermarket DPC version 1.0.0 characterized as HTTP Response Splitting, classified under CWE-113 (Improper Control of HTTP Messages and Headers). This vulnerability occurs when the application fails to properly sanitize or validate user-supplied input that is incorporated into HTTP response headers. An attacker can exploit this by injecting CR (Carriage Return) and LF (Line Feed) characters into HTTP headers, causing the server to split the response into multiple headers or responses. Depending on the application's handling of these split responses, this can lead to arbitrary command execution or injection of malicious content such as cross-site scripting (XSS) payloads or cache poisoning. The CVSS 3.1 base score of 3.1 reflects a low severity due to the requirement of user interaction, high attack complexity, and limited impact on confidentiality only, with no effect on integrity or availability. No known exploits have been reported in the wild, and no official patches are currently available. The vulnerability is remotely exploitable without authentication, but the attacker must trick a user into interacting with a crafted HTTP response. This flaw highlights the importance of rigorous input validation and secure HTTP header construction in web applications.
