HCL vulnerabilities and threats

HCL Aftermarket DPC is affected by Banner Disclosure vulnerability where attackers gain insights into the system’s software and version details which would allow them to craft software specific attacks.

HCL Aftermarket DPC is affected by Cross Domain Script Include vulnerability where an attacker using external scripts can tamper with the DOM, altering the content or behavior of the application. Malicious scripts can steal cookies or session tokens, leading to session hijacking.

HCL Aftermarket DPC is affected by Cross-Origin Resource Sharing vulnerability. CORS misconfigurations includes the exposure of sensitive user information to attackers, unauthorized access to APIs, and possible data manipulation or leakage. If an attacker to exploit CORS misconfiguration, they could steal sensitive data, perform actions on behalf of a legitimate user.

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.

HCL Aftermarket DPC is affected by Internal IP Disclosure vulnerability will give attackers a clearer map of the organization’s network layout.

HCL Aftermarket DPC is affected by Use of Vulnerable/Outdated Versions vulnerability using which an attacker may make use of the exploits available across the internet and craft attacks against the application.

HCL Traveler is susceptible to a weak default HTTP header validation vulnerability, which could allow an attacker to bypass additional authentication checks.

CVE-2026-21783 is a medium-severity vulnerability in HCLSoftware Traveler versions prior to 14.5.1.0, where error messages disclose sensitive information such as internal paths, file names, tokens, credentials, error codes, or stack traces. This information disclosure can aid attackers in understanding system architecture and crafting targeted attacks. The vulnerability does not require user interaction but does require some level of privileges (PR:L). There are no known exploits in the wild currently. The CVSS score is 4.3, reflecting limited confidentiality impact without direct integrity or availability effects. Organizations using affected versions should update to 14.

HCL Connections is vulnerable to a cross-site scripting attack where an attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user which leads to executing malicious script code.  This may allow the attacker steal cookie-based authentication credentials and comprise user's account then launch other attacks.

A Stored cross-site scripting (XSS) vulnerability affects HCL Unica Marketing Operations v12.1.8 and lower.  Stored cross-site scripting (also known as second-order or persistent XSS) arises when an application receives data from an untrusted source and includes that data within its later HTTP responses in an unsafe way.

HTML Injection can be carried out in Product when a web application does not properly check or clean user input before showing it on a webpage. Because of this, an attacker may insert unwanted HTML code into the page. When the browser loads the page, it may automatically interact with external resources included in that HTML, which can cause unexpected requests from the user’s browser.

HCL Sametime is vulnerable to broken server-side validation. While the application performs client-side input checks, these are not enforced by the web server. An attacker can bypass these restrictions by sending manipulated HTTP requests directly to the server.

CVE-2025-62319 is a critical SQL injection vulnerability affecting HCL Unica versions 25.1.1 and below. It involves Boolean-based blind SQL injection, where attackers inject Boolean conditions into input fields to manipulate backend SQL queries without triggering visible errors. This flaw allows attackers to execute arbitrary SQL commands, potentially compromising database confidentiality, integrity, and availability. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. Although no known exploits are currently reported in the wild, the high CVSS score of 9.8 indicates severe risk. Organizations using affected versions of HCL Unica should prioritize patching or applying mitigations to prevent data breaches, unauthorized data manipulation, or service disruption. Countries with significant deployments of HCL Unica and strategic interest in marketing automation platforms are at higher risk.

HCL AION is affected by a vulnerability where internal filesystem paths may be exposed through application responses or system behaviour. Exposure of internal paths may reveal environment structure details which could potentially aid in further targeted attacks or information disclosure.

HCL AION is affected by a vulnerability where certain offering configurations may permit execution of potentially harmful SQL queries. Improper validation or restrictions on query execution could expose the system to unintended database interactions or limited information exposure under specific conditions.

HCL AION is affected by a vulnerability where model packaging and distribution mechanisms may not include sufficient authenticity verification. This may allow the possibility of unverified or modified model artifacts being used, potentially leading to integrity concerns or unintended behaviour.

HCL AION is affected by a vulnerability where certain identifiers may be predictable in nature. Predictable identifiers may allow an attacker to infer or guess system-generated values, potentially leading to limited information disclosure or unintended access under specific conditions.

HCL AION is affected by a vulnerability where certain user actions are not adequately audited or logged. The absence of proper auditing mechanisms may reduce traceability of user activities and could potentially impact monitoring, accountability, or incident investigation processes.

HCL AION is affected by a vulnerability where untrusted file parsing operations are not executed within a properly isolated sandbox environment. This may expose the application to potential security risks, including unintended behaviour or integrity impact when processing specially crafted files.

HCL AION is affected by a vulnerability related to the handling of upload size limits. Improper control or validation of upload sizes may allow excessive resource consumption, which could potentially lead to service degradation or denial-of-service conditions under certain scenarios.
