CVE-2023-37507 Overview
CVE-2023-37507 is an information disclosure vulnerability affecting HCL DevOps Plan. The flaw exposes internal application data to unauthenticated network attackers. Attackers can leverage the disclosed information to refine follow-on attacks against the target environment.
The vulnerability is categorized under [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere. It carries a CVSS 4.0 base score of 6.9 with a network attack vector requiring no authentication or user interaction. While confidentiality impact is limited, the disclosed data can accelerate reconnaissance and enable more targeted exploitation attempts.
Critical Impact
Unauthenticated remote attackers can retrieve sensitive system information from HCL DevOps Plan, enabling reconnaissance and targeted follow-on attacks against the affected deployment.

Technical Details for CVE-2023-37507
Vulnerability Analysis
HCL DevOps Plan discloses sensitive system information to unauthenticated remote clients. The exposure is reachable over the network without any privileges or user interaction. The disclosed content itself does not directly compromise data integrity or availability, but it substantially improves an attacker's ability to plan subsequent exploitation.
Information disclosure vulnerabilities of this class typically expose runtime metadata, stack traces, configuration paths, software versions, or internal identifiers. This intelligence allows attackers to fingerprint the deployment, enumerate installed components, and identify known vulnerabilities that match the disclosed versions. It also narrows the attack surface an adversary must probe blindly.
Root Cause
The root cause maps to [CWE-497], Exposure of Sensitive System Information to an Unauthorized Control Sphere. The application returns internal data in responses accessible to unauthorized users. This typically results from verbose error handling, debug output left enabled in production, or missing access controls on informational endpoints.
Attack Vector
An unauthenticated attacker sends crafted network requests to an exposed HCL DevOps Plan instance. The server returns responses containing sensitive system information. No user interaction is required, and attack complexity is low. HCL has not disclosed public proof-of-concept exploit code, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
See the HCL Software Knowledge Base Article for vendor technical details.
Detection Methods for CVE-2023-37507
Indicators of Compromise
- Anomalous unauthenticated HTTP requests targeting HCL DevOps Plan diagnostic, status, or error-generating endpoints
- Repeated requests from a single external source enumerating application paths and parameters
- Response payloads containing stack traces, version strings, or internal file paths returned to external clients
Detection Strategies
- Inspect web server and application logs for requests that generate verbose error responses or expose metadata
- Baseline normal traffic patterns to HCL DevOps Plan and alert on unusual reconnaissance-style request bursts
- Deploy web application firewall rules to flag response bodies containing indicators such as stack traces or configuration data
Monitoring Recommendations
- Forward HCL DevOps Plan access and application logs to a centralized SIEM for correlation and retention
- Alert on scanner user-agent strings and known reconnaissance tooling signatures targeting the application
- Monitor egress response sizes for anomalies that may indicate bulk information disclosure
How to Mitigate CVE-2023-37507
Immediate Actions Required
- Apply the fix documented in the HCL Software Knowledge Base Article to all affected HCL DevOps Plan deployments
- Restrict network access to HCL DevOps Plan instances so only trusted users and networks can reach the application
- Audit recent logs for reconnaissance activity that may indicate prior exploitation attempts
Patch Information
HCL has published remediation guidance in knowledge base article KB0132309. Administrators should consult the HCL Software Knowledge Base Article for the specific fixed versions and upgrade instructions applicable to their deployment.
Workarounds
- Place HCL DevOps Plan behind a reverse proxy or web application firewall that strips sensitive information from responses
- Disable verbose error messages and debug output in production configurations
- Enforce network-layer access controls limiting exposure to authenticated, trusted users only
