CVE-2025-31981: CWE-319 Cleartext transmission of sensitive information in HCLSoftware BigFix Service Management (SM)
CVE-2025-31981 is a medium severity vulnerability in HCL BigFix Service Management (SM) version 23 where sensitive information can be transmitted in cleartext due to the service listening on port 80 (HTTP) without enforced encryption. This allows an attacker with network access to sniff unencrypted traffic and potentially uncover sensitive data. There is no official patch or remediation level currently provided by the vendor. The vulnerability does not affect cloud services and no known exploits are reported in the wild.
AI Analysis
Technical Summary
HCL BigFix Service Management (SM) Discovery component in version 23 exposes sensitive information over an unencrypted HTTP connection on port 80. Because encryption is not enforced, network attackers can intercept and read sensitive data transmitted between clients and the service. The CVSS 3.1 base score is 5.3 (medium severity) reflecting network attack vector, low complexity, no privileges or user interaction required, and limited confidentiality impact. No official fix or mitigation guidance is currently available from HCLSoftware.
Potential Impact
An attacker with access to the network traffic can capture unencrypted packets transmitted over HTTP and obtain sensitive information. The confidentiality of data is impacted, but integrity and availability are not affected. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to disable HTTP access on port 80 and enforce HTTPS to ensure encryption of data in transit. Network segmentation or use of VPNs to restrict access to the service may reduce exposure.
