Quick assessment

Affected
Tobit Laboratories AG TeamDavid
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Tobit Laboratories TeamDavid WebBox是Tobit Laboratories公司的一个提供邮件、消息及存档数据远程访问功能的独立Web服务器模块。 Tobit Laboratories TeamDavid WebBox Rollout 524及之前版本存在安全漏洞，该漏洞源于链接存储功能（//ServerClient_celink.htm）对pathname参数未进行验证，攻击者无需认证即可利用该参数设置UNC路径，导致服务器向攻击者控制的SMB服务器发起认证，从而暴露NT

Vulnerability Title
TeamDavid: Server-Side Request Forgery (SSRF) via 'pathname' parameter in link storing functionality
Source: CVE Program / CVE List V5
Vulnerability Description
Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality (//ServerClient_celink.htm) accepts a “pathname” parameter, which can be set to network locations using UNC paths (e.g., “\\Server\Share”). The server processes these paths without validation, resulting in outbound connection attempts to attacker-controlled SMB servers. This enables authenticated attackers to trigger the server to authenticate to arbitrary SMB endpoints, potentially exposing NTLM authentication information (such as NTLM hashes). If outbound connections to port 445 (SMB) are permitted, attackers can use this to conduct SMB relay or credential theft attacks. Exploitation of the “pathname” parameter is possible without authentication. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.
