CVE-2026-58451— Horde imp 路径遍历漏洞

Horde IMP < 7.0.1 Path Traversal via Compose.php img src

Horde IMP before 7.0.1 contains a path traversal vulnerability in lib/Compose.php that allows authenticated attackers to read arbitrary files from the server filesystem by embedding traversal sequences after a CKEditor path prefix in img src URLs. Attackers can bypass the stripos() prefix validation by appending sequences such as traversal segments after the matching prefix, causing file_get_contents() to read sensitive files whose contents are then exfiltrated as MIME parts in outgoing email; unauthenticated exploitation is also achievable via CSRF against an active authenticated session.

对路径名的限制不恰当(路径遍历)

Horde imp 路径遍历漏洞

Horde imp是Horde组织开源的一个基于 web 的网络邮件系统。 Horde imp 7.0.1之前版本存在路径遍历漏洞，该漏洞源于lib/Compose.php存在路径遍历问题，允许经过身份验证的攻击者通过在img src URL的CKEditor路径前缀后嵌入遍历序列来读取服务器文件系统中的任意文件。攻击者可绕过stripos()前缀验证，导致file_get_contents()读取敏感文件并作为MIME部分渗漏到外发邮件中；未经身份验证的攻击也可通过对活动的已验证会话进行CSRF来实现。
