CVE-2026-33488— WWBN AVideo 加密问题漏洞

AVideo has a PGP 2FA Bypass via Cryptographically Broken 512-bit RSA Key Generation in LoginControl Plugin

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `createKeys()` function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the 512-bit RSA modulus on commodity hardware in hours, derive the complete private key, and decrypt any PGP 2FA challenge issued by the system — completely bypassing the second authentication factor. Additionally, the `generateKeys.json.php` and `encryptMessage.json.php` endpoints lack any authentication checks, exposing CPU-intensive key generation to anonymous users. Commit 00d979d87f8182095c8150609153a43f834e351e contains a patch.

不充分的加密强度

WWBN AVideo 加密问题漏洞

WWBN AVideo是WWBN团队的一个由PHP编写的视频平台建站系统。 WWBN AVideo 26.0及之前版本存在加密问题漏洞，该漏洞源于使用弱RSA密钥且端点缺少身份验证，可能导致绕过双因素身份验证和拒绝服务攻击。
