CVE-2025-31975 represents a low-severity vulnerability affecting HCL BigFix Service Management (SM). The vulnerability is characterized as an information disclosure issue related to server banners. When exposed, these banners can reveal software versions and system details, potentially aiding attackers in targeting known vulnerabilities. The CVSS score associated with this vulnerability is 2.6, indicating a low severity level, which necessitates awareness but does not imply immediate critical risk.
The exploitability of this vulnerability is low, and it is categorized under CWE-200, which pertains to information exposure. Although the vulnerability does not currently have known exploits or public proof-of-concept (PoC) details, the risk to organizations includes potential targeted attacks leveraging disclosed version information. Therefore, organizations should prioritize remediation based on their risk tolerance and operational environment.
Given the nature of this vulnerability, organizations utilizing HCL BigFix SM should assess their configurations to ensure that server banners are appropriately managed and restricted. Immediate action is advisable to maintain a secure environment and reduce the risk of information disclosure.
Urgency for defenders is moderate; while the threat level is low, the potential for attackers to exploit any revealed information should not be overlooked. Organizations are encouraged to integrate this assessment into their vulnerability management programs and to remain vigilant against any attempts to exploit this or similar vulnerabilities.
Vulnerability Details
HCL BigFix Service Management (SM) is impacted by an information disclosure vulnerability due to exposed server banners. The official CVE description highlights that these banners may reveal sensitive software versions and system details, which could assist attackers in targeting known vulnerabilities. The vulnerability is classified under CWE-200, indicating that it falls under the category of information exposure.
The vulnerability has a CVSS score of 2.6, indicating a low severity level. The attack vector is categorized as adjacent network, with an attack complexity of high. No privileges are required for exploitation, and user interaction is necessary. The confidentiality impact is low, while there are no integrity or availability impacts associated with this vulnerability.
The vulnerability was published on May 6, 2026, and affects all versions of HCL BigFix Service Management prior to the vendor patch. Organizations should take immediate steps to review their configurations and ensure that server banners do not expose sensitive information.
Technical Analysis
The root cause of CVE-2025-31975 is the improper handling of server banners that may reveal sensitive software information. This vulnerability can be exploited in scenarios where an attacker is on the same adjacent network and able to send requests to the server hosting HCL BigFix SM.
The attack vector is classified as adjacent network, indicating that an attacker must be on the same local network segment as the vulnerable system. The attack complexity is categorized as high, meaning that specific conditions must be met to exploit the vulnerability. No special privileges are required, and user interaction is necessary to access the exposed information. The confidentiality impact is low, as the exposed data primarily pertains to software versions without compromising sensitive personal or organizational data.
Risk & Impact Analysis
The risk to organizations includes potential targeted attacks that leverage disclosed software versions and system details. Although CVE-2025-31975 has a low severity rating, the implications of information exposure can lead to increased vulnerability to subsequent attacks if attackers are able to exploit known vulnerabilities associated with exposed software.
Organizations should assess the impact of this vulnerability on their operational environment, particularly those with critical systems that rely on HCL BigFix SM. The potential blast radius is moderate, as multiple systems may be affected if the information is leveraged by attackers.
Given the CVSS score of 2.6, the urgency for remediation is moderate. Organizations should schedule remediation efforts to address this vulnerability in their patch management cycles, ensuring that server banner information is appropriately restricted to prevent information leaks.
