Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.79% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Tasin1025 SwiftBuy and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

01

What, why and how

A security flaw has been discovered in Tasin1025 SwiftBuy up to 0f5011372e8d1d7edfd642d57d721c9fadc54ec7. Affected by this vulnerability is an unknown functionality of the file /login.php. Performing a manipulation results in improper restriction of excessive authentication attempts. Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitation appears to be difficult. The exploit has been released to the public and may be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The vendor was contacted early about this disclosure but did not respond in any way.

What

A security flaw has been discovered in Tasin1025 SwiftBuy up to 0f5011372e8d1d7edfd642d57d721c9fadc54ec7. Affected by this vulnerability is an unknown functionality of the file /login.php. Performing a manipulation results in improper restriction of excessive authentication attempts. Remote exploitation of the attack is possible. The attack's complexity is rated as high. The exploitation appears to be difficult. The exploit has been released to the public and may be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The vendor was contacted early about this disclosure but did not respond in any way.

Why

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path
a network path → Improper Restriction of Excessive Authentication Attempts → cause the confidentiality, integrity or availability impact described by the vendor
