Security readout for executives and security teams
Plain-English summary
CVE-2022-23790 is a cross-site scripting issue in Firmanet Software and Technology Customer Relation Manager before 2022.03.13. An attacker could cause a user to run unwanted script in their browser, potentially exposing limited data or altering what the user sees. It is rated medium severity by CVSS.
Executive priority
Treat as a normal-priority remediation for any affected CRM handling customer data. It is not currently supported as actively exploited in the provided sources, but customer-facing or internet-accessible deployments should be updated promptly.
Technical view
The issue is CWE-79 improper neutralization during web page generation. CVSS 3.1 is 6.1: network exploitable, low complexity, no attacker privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Organizations using Firmanet Customer Relation Manager versions before 2022.03.13 are the relevant exposure. Risk is higher if the CRM is internet-accessible or used by staff with access to sensitive customer records.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires user interaction, consistent with a victim viewing or following attacker-controlled content that triggers script execution in the CRM context.
Researcher notes
Public details are sparse. The CVE identifies XSS and the affected version range, but does not specify the vulnerable parameter, module, or patch mechanics. One USOM reference is tagged as broken in the bundle; use the surviving government advisory and vendor guidance for confirmation.
Mitigation direction
- Identify any Firmanet Customer Relation Manager deployments and their version dates.
- Ensure deployments are not running versions before 2022.03.13.
- Check Firmanet or government advisory guidance for the confirmed fixed release.
- Reduce external exposure of the CRM where business needs allow.
- Use browser and application security controls that limit XSS impact.
Validation and detection
- Confirm product name and version from asset inventory or application administration.
- Compare installed version against the affected range: before 2022.03.13.
- Review vendor or advisory pages for updated remediation details.
- Check web access logs for unusual CRM requests around user-reported browser events.
- Verify remediation in a test environment before production rollout.

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.
