Security readout for executives and security teams
Plain-English summary
Onest CRM 1.0 has an authenticated cross-site scripting issue in the project update area. A malicious user with access could place script content in a project name, potentially affecting another user viewing that content. The sources do not identify active exploitation or a vendor fix.
Executive priority
Treat as a moderate-priority application security issue. It is not currently supported by evidence of active exploitation, but it can affect user trust and session safety if authenticated users can inject content into shared CRM pages.
Technical view
CVE-2023-3505 is CWE-79 in Onest CRM 1.0, affecting the Project List Handler at /admin/project/update/2. The reported vector is the name argument. CVSS v2 is 4.0 with network access, low complexity, and authentication required. Vendor response and fixed versions are not documented.
Likely exposure
Exposure appears limited to organizations running Onest CRM 1.0, especially where untrusted or lower-privileged authenticated users can update project names. The source data provides no CPEs, deployment prevalence, or affected version range beyond 1.0.
Exploitation context
The issue is remotely triggerable but requires authentication according to the CVSS vector. Public vulnerability records describe the vulnerable parameter, but the provided sources do not show KEV listing, confirmed exploitation in the wild, or weaponized exploit activity.
Researcher notes
Evidence is sparse: VulDB reports the affected component, route, and parameter, while CVE data confirms CWE-79 and CVSS v2 scoring. The vendor reportedly did not respond, and no fixed version or official mitigation is named in the provided sources.
Mitigation direction
- Identify whether Onest CRM 1.0 is deployed in any environment.
- Check vendor or project guidance for an official update or replacement path.
- Restrict project administration access to trusted users until remediated.
- For maintained forks, review contextual output encoding and input handling for project names.
Validation and detection
- Inventory CRM instances and confirm the deployed Onest CRM version.
- Verify whether /admin/project/update/2 or equivalent project update functionality is present.
- Review project name rendering for proper encoding in authenticated staging tests.
- Check access controls for users allowed to create or update project names.

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.
