Security readout for executives and security teams
Plain-English summary
CVE-2025-7799 is a reflected cross-site scripting issue in Zirve Information Technologies' e-Taxpayer Accounting Website through 07082025. Affected deployments could let attacker-controlled input influence a web page response, risking data exposure or unauthorized actions in a user context. The source bundle does not identify a confirmed patch.
Executive priority
Prioritize this for affected tax or accounting portals, especially internet-facing systems. The business risk is unauthorized content execution in a trusted financial workflow, but urgency depends on whether your organization runs this specific Zirve website version.
Technical view
The record maps to CWE-79 and carries CVSS 3.1 score 8.6, vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L. The described flaw is improper input neutralization during web page generation, resulting in reflected XSS in the e-Taxpayer Accounting Website through 07082025.
Likely exposure
Exposure is limited to organizations using Zirve Information Technologies' e-Taxpayer Accounting Website at versions through 07082025. The provided CPE data is empty and the affected version field is sparse, so asset matching may require vendor-specific inventory checks.
Exploitation context
The source bundle does not show CISA KEV listing, confirmed active exploitation, public exploit details, or weaponized guidance. Treat this as high priority because it is remotely reachable, low complexity, and affects integrity according to the CVSS vector.
Researcher notes
Evidence is limited to the CVE metadata and government advisory references. The USOM link is tagged as broken in the bundle, while the siberguvenlik.gov.tr advisory is listed as a government resource. No fix version, exploit status, or affected CPEs are provided.
Mitigation direction
- Check Zirve and government advisories for a fixed release or official mitigation.
- Prioritize upgrading any deployment at or before 07082025 if an update is available.
- Apply contextual output encoding and input neutralization in affected web code.
- Use temporary monitoring or filtering controls while awaiting vendor guidance.
Validation and detection
- Inventory all Zirve e-Taxpayer Accounting Website deployments and record deployed version dates.
- Confirm whether any instance is through 07082025.
- Review vendor or government advisory status for updated remediation guidance.
- Perform authorized XSS-safe validation of reflected input handling without weaponized payloads.
- Review logs for suspicious parameterized requests targeting public pages.

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.
