CVE-2025-55267 affects HCL Aftermarket DPC and is classified as an unrestricted file upload vulnerability. This vulnerability allows an attacker to upload and execute malicious scripts, thereby gaining full control over the server. The medium severity score of 5.7 indicates a moderate level of risk to organizations, necessitating prompt attention.
The vulnerability was published on March 26, 2026, and is associated with a CVSS base score of 9.8, indicating potential critical impacts in specific contexts. Organizations using affected systems should be aware of the risks associated with this vulnerability, particularly regarding data integrity concerns, as attackers may exploit this flaw to manipulate or steal sensitive information.
As such, organizations should prioritize patching immediately to mitigate the risks posed by this vulnerability. Additionally, there is currently no known public exploit, which provides a temporary respite for defenders, but vigilance is essential.
Organizations should assess their environments to identify any instances of HCL Aftermarket DPC and prepare for remediation actions to ensure their systems remain secure.
Vulnerability Details
The official description of CVE-2025-55267 states that the vulnerability allows the upload and execution of malicious scripts due to unrestricted file upload functionality. This flaw, classified as CWE-434, can lead to significant integrity impacts, as attackers can manipulate the server's behavior.
The CVSS score from the NVD indicates a critical level of risk with a base score of 9.8, while the HCL PSIRT provides a lower score of 5.7. This discrepancy highlights the importance of context in assessing vulnerability severity, particularly regarding potential impacts on confidentiality, integrity, and availability.
The affected product is HCL Aftermarket Cloud, specifically version 1.0.0. Organizations using this version should take immediate steps to mitigate the risk.
Technical Analysis
The root cause of this vulnerability is the lack of proper validation for file uploads, allowing an attacker to upload files that can be executed on the server. This vulnerability is exploitable over the network, requires low attack complexity, and only low privileges are necessary for exploitation.
User interaction is required, as the successful execution of the attack depends on a user triggering the upload process. The integrity impact is rated as high, indicating that attackers may alter data or configurations on the server, potentially leading to further security issues.
There is no confidentiality or availability impact, which means the attack does not affect the confidentiality of data or the availability of the server itself but can significantly compromise the integrity of the system.
Risk & Impact Analysis
Risk to organizations includes the potential for attackers to gain unauthorized access and control over servers running HCL Aftermarket DPC. The blast radius could extend beyond the initial server to affect connected systems and data, leading to further security incidents.
The urgency for organizations to address this vulnerability is high due to the potential risks associated with the unrestricted file upload capability. As the CVSS score indicates a medium severity level, organizations should address in priority patch cycle.
