Short explanation
Multiple WSO2 products contain a vulnerability caused by the refresh token grant type failing to re-validate account status. This weakness allows attackers to obtain valid access tokens for blocked accounts, bypassing account lockout mechanisms.
It enables unauthorized access to blocked user accounts, potentially allowing attackers to perform actions on behalf of blocked users, escalate privileges, or exfiltrate data.
What should be done?
- Follow the vendor security advisory
- Apply available updates for affected products
Chain of evidence and sources
WSO2 ürünlerindeki yenileme token grant türü, yeni erişim token'ları düzenlemeden önce hesap durumunu yeniden doğrulamamaktadır.
Bu zafiyet, kullanıcı deposu tarafından engellenen hesaplar için dahi geçerli erişim token'ları alınmasına ve hesap kilitleme mekanizmalarının atlanmasına neden olur.
Show the technical text from the sources
The refresh token grant type in WSO2 products fails to re-validate account status before issuing new access tokens. This weakness allows an attacker to obtain valid access tokens for user accounts even after they have been blocked by the user store, bypassing account lockout mechanisms. This vulnerability can lead to unauthorized access to user accounts and their associated resources. Attackers can leverage this to perform actions on behalf of blocked users, potentially leading to privilege escalation or data exfiltration depending on the permissions of the compromised account.
