CVE-2025-31981 is a medium-severity vulnerability affecting HCL BigFix Service Management (SM) Discovery. This vulnerability allows unencrypted access due to the exposure of port 80 (HTTP), which can be exploited by an attacker who has access to the network traffic. The risk is significant as attackers may leverage this vulnerability to sniff packets and uncover sensitive data transmitted over the connection.
The vulnerability has a CVSS score of 5.3, indicating a medium level of severity. This score suggests a moderate risk to organizations, particularly those utilizing HCL products in their infrastructure. The presence of unencrypted data can lead to unauthorized access and potential data breaches, making this a pressing concern for security teams.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The unencrypted nature of HTTP traffic can expose sensitive data, increasing the likelihood of data leakage. It is crucial for organizations to assess their current configurations and apply necessary updates to safeguard their systems.
As of now, there are no known exploits or public proof-of-concept (PoC) available for this vulnerability. However, it is important to remain vigilant and monitor any emerging threats associated with CVE-2025-31981. Timely remediation efforts can help prevent potential exploitation and protect sensitive information.
Vulnerability Details
HCL BigFix Service Management (SM) Discovery is vulnerable to unenforced encryption due to port 80 (HTTP) being open, allowing unencrypted access. An attacker with access to the network traffic can sniff packets from the connection and uncover the data.
The CVSS score for this vulnerability is 5.3, classified as medium severity. The vulnerability is classified under CWE-319, which pertains to the lack of encryption for sensitive data in transit.
Technical Analysis
The root cause of this vulnerability is the unenforced encryption due to the presence of an open HTTP port. This lack of encryption enables attackers to intercept and analyze network traffic. The attack vector is network-based, with low complexity, requiring no privileges or user interaction to exploit.
The vulnerability has a confidentiality impact rated as low, meaning that while sensitive data may be exposed, it does not necessarily imply a complete loss of confidentiality. Integrity and availability impacts are assessed as none, indicating that the vulnerability does not affect the integrity of the data or the availability of the service.
Risk & Impact Analysis
The real-world deployment risk for this vulnerability is moderate due to the potential for data exposure. Organizations that rely on HCL BigFix Service Management should be particularly cautious, as attackers may attempt to exploit the open HTTP port to gain access to sensitive information. The potential for unauthorized access to sensitive data increases the urgency for organizations to address this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected version of the product is HCL BigFix Service Management version 23.0. Organizations utilizing this version should ensure they apply the necessary patches to mitigate this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching immediately. HCL has provided patch information through their advisory, which is critical for remediation. If a patch is not available, organizations should consider implementing workarounds such as enforcing HTTPS to secure data in transit. Additionally, configuring network controls to restrict access to sensitive services and monitoring network traffic for anomalies can further help mitigate risks.
Detection Guidance
To detect potential exploitation, organizations should monitor logs for unusual access patterns to HTTP services. Behavioral anomalies may indicate attempts to capture unencrypted data. Network signatures should be updated to detect any unauthorized access attempts, and system changes should be closely monitored to identify any unauthorized modifications.
AppSecure Threat Intelligence Insight
