Versions of Coverity Connect prior to 2022.12.0 are vulnerable to an unauthenticated Cross-Site Scripting vulnerability. Any web service hosted on the same sub domain can set a cookie for the whole subdomain which can be used to bypass other mitigations in place for malicious purposes.

Security readout for executives and security teams

Plain-English summary

Coverity Connect versions before 2022.12.0 have an unauthenticated cross-site scripting issue. A related same-subdomain cookie behavior can undermine other protections and may allow serious compromise of confidentiality, integrity, and availability. Organizations using older Coverity Connect should prioritize upgrade validation.

Executive priority

Treat as a high-priority product upgrade for teams using Coverity Connect. The vulnerability is not confirmed as actively exploited in the provided sources, but the unauthenticated path and high impact justify prompt remediation.

Technical view

CVE-2023-23849 is CWE-79 in Synopsys Coverity Connect before 2022.12.0. The CVSS 3.1 score is 8.1 with network attack vector, no privileges, no user interaction, high attack complexity, and high C/I/A impact. The source bundle does not identify a specific endpoint.

Likely exposure

Exposure is limited to Synopsys Coverity Connect deployments running versions earlier than 2022.12.0. Risk is higher when the Coverity Connect web service is reachable by untrusted networks or shares a subdomain with other hosted services.

Exploitation context

The source bundle says this is unauthenticated and network-reachable but high complexity. It is not listed as CISA KEV, and the provided sources do not state active exploitation or public exploit availability.

Researcher notes

The available public details are sparse. The advisory and CVE data establish affected versions, class, and CVSS vector, but not endpoint-level behavior or detection indicators. Avoid assuming exploitability beyond the documented same-subdomain cookie condition.

Mitigation direction

  • Upgrade Coverity Connect to 2022.12.0 or later following Synopsys guidance.
  • Check the Synopsys advisory for any product-specific remediation notes.
  • Reduce untrusted network access to Coverity Connect until upgraded.
  • Review same-subdomain web services and cookie scoping for avoidable trust overlap.

Validation and detection

  • Inventory all Coverity Connect instances and record exact versions.
  • Confirm no production instance is older than 2022.12.0.
  • Review whether Coverity Connect is internet-facing or broadly reachable internally.
  • Identify other web services hosted on the same subdomain.
  • Check security monitoring for suspicious Coverity Connect web activity.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
