Employee Performance Evaluation System v1.0 was discovered to contain a persistent cross-site scripting (XSS) vulnerability via adding new entries under the Departments and Designations module.
Security readout for executives and security teams
Plain-English summary
CVE-2022-40435 is a stored cross-site scripting issue in Employee Performance Evaluation System v1.0. A privileged user can save malicious content in Departments or Designations entries, which may later run in another user’s browser. Business risk is moderate because exploitation requires high privileges and user interaction, but it can affect confidentiality and integrity.
Executive priority
Prioritize if this application is used internally with sensitive HR data or has internet-accessible administration. Otherwise handle through normal remediation because exploitation requires privileged access and user interaction.
Technical view
The CVE describes persistent XSS, CWE-79, in the Departments and Designations module when adding new entries. CVSS 3.1 is 4.8: AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N. The sources do not identify a CPE, vendor-maintained patch, or broader affected version range.
Likely exposure
Exposure is limited to organizations running Employee Performance Evaluation System v1.0 or derived deployments where authenticated high-privilege users can create Department or Designation records. Internet-facing admin panels increase concern, but the sources do not confirm deployment prevalence.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. Reported exploitation requires authenticated high privileges and a victim viewing affected stored content. Treat this as a stored XSS weakness rather than confirmed mass exploitation.
Researcher notes
Evidence is sparse: the CVE names the product and modules, but the affected CPE fields are n/a and no patch details are provided. Avoid assuming other versions are affected without code comparison or vendor confirmation.
Mitigation direction
Check SourceCodester/project guidance for any maintained fix or updated package.
Restrict administrative access to trusted users and networks.
Sanitize and encode Department and Designation values before storage and display.
Review existing records for suspicious markup and remove unsafe content.
Add server-side validation for text fields in affected modules.
Validation and detection
Inventory deployments and confirm whether Employee Performance Evaluation System v1.0 is present.
Review Departments and Designations creation paths for output encoding.
Inspect stored Department and Designation records for unexpected scriptable content.
Test in a non-production environment using harmless markers only.
Confirm authenticated role requirements for adding affected entries.

CWE-79: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
