CVE-2026-10303— ServerCo getssl 输入验证错误漏洞

ServerCo getssl ACME shell script path injection

In ServerCo getssl version 2.49 and prior, the ACME challenge token returned to the client was not strictly validated against RFC 8555 before being used in challenge-file handling, allowing a maliciously crafted token to influence local path/filename usage during validation. An attacker who can supply ACME challenge responses to getssl (for example, a malicious or compromised CA endpoint, or an on-path adversary able to tamper with that response path) could exploit this to achieve unauthorized file write/path traversal effects, usually with elevated privileges, ultimately allowing for remote command injection. This issue appears related in spirit to CVE-2023-38198, and is an instance of CWE-73, "External control of file name or path." Other ACME shell script handlers may be affected by similar issues.

文件名或路径的外部可控制

ServerCo getssl 输入验证错误漏洞

getssl是ServerCo组织开源的一个服务器端SSL证书管理软件。 ServerCo getssl 2.49及之前版本存在输入验证错误漏洞，该漏洞源于对ACME挑战令牌验证不当，导致外部控制文件名或路径，可能允许攻击者实现未授权文件写入或路径遍历效果，通常具有提升的权限，最终可能导致远程命令注入。
