CVE-2026-35098 (GCVE-0-2026-35098)
Vulnerability from nvd – Published: 2026-06-30 13:37 – Updated: 2026-06-30 14:40
VLAI
Title
Improper Restriction of Excessive Authentication Attempts in KTM System e-BOK
Summary
KTM System e-BOK does not implement any limit or timeout on consecutive login attempts, allowing an attacker to perform unlimited authentication requests. This lack of rate‑limiting enables efficient brute‑force attacks against user accounts. When combined with vulnerability CVE-2026-35097, where passwords are restricted to a six‑digit numeric format, this becomes a critical issue, as such passwords can be brute‑forced in a relatively short time.
This issue was fixed in the patch published in June 2026.

CVE-2026-35096 (GCVE-0-2026-35096)

Title
Cross-Site Request Forgery (CSRF) in KTM System e-BOK
Summary
KTM System e-BOK is vulnerable to Cross‑Site Request Forgery (CSRF) in both the email-change and password-change functionalities. An attacker can craft a malicious website that, when visited by an authenticated user, automatically sends a forged POST request to the application. This allows the attacker to trigger an unauthorized email or password change on behalf of the victim without their knowledge or interaction.
This issue was fixed in the patch published in June 2026.

Title
Session fixation in KTM System e-BOK
Summary
KTM System e-BOK allows the session identifier to be set by the client prior to authentication. If a cookie with a valid name is set, its value remains unchanged after successful login. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session.
This issue was fixed in the patch published in June 2026.

CVE-2026-35098 (GCVE-0-2026-35098)
Vulnerability from cvelistv5 – Published: 2026-06-30 13:37 – Updated: 2026-06-30 14:40

Title
Improper Restriction of Excessive Authentication Attempts in KTM System e-BOK
Summary
KTM System e-BOK does not implement any limit or timeout on consecutive login attempts, allowing an attacker to perform unlimited authentication requests. This lack of rate‑limiting enables efficient brute‑force attacks against user accounts. When combined with vulnerability CVE-2026-35097, where passwords are restricted to a six‑digit numeric format, this becomes a critical issue, as such passwords can be brute‑forced in a relatively short time.
This issue was fixed in the patch published in June 2026.

Title
Cross-Site Request Forgery (CSRF) in KTM System e-BOK
Summary
KTM System e-BOK is vulnerable to Cross‑Site Request Forgery (CSRF) in both the email-change and password-change functionalities. An attacker can craft a malicious website that, when visited by an authenticated user, automatically sends a forged POST request to the application. This allows the attacker to trigger an unauthorized email or password change on behalf of the victim without their knowledge or interaction.
This issue was fixed in the patch published in June 2026.

Title
Session fixation in KTM System e-BOK
Summary
KTM System e-BOK allows the session identifier to be set by the client prior to authentication. If a cookie with a valid name is set, its value remains unchanged after successful login. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session.
This issue was fixed in the patch published in June 2026.
