Описание
Incorrect Authorization vulnerability in Erlang OTP (inets modules) allows unauthenticated access to CGI scripts protected by directory rules when served via script_alias.
When script_alias maps a URL prefix to a directory outside DocumentRoot, mod_auth evaluates directory-based access controls against the DocumentRoot-relative path while mod_cgi executes the script at the ScriptAlias-resolved path. This path mismatch allows unauthenticated access to CGI scripts that directory rules were meant to protect.
This vulnerability is associated with program files lib/inets/src/http_server/mod_alias.erl, lib/inets/src/http_server/mod_auth.erl, and lib/inets/src/http_server/mod_cgi.erl.
This issue affects OTP from OTP 17.0 before OTP 28.4.2, OTP 27.3.4.10 and OTP 26.2.5.19, corresponding to inets from 5.10 before 9.6.2, 9.3.2.4 and 9.1.0.6.
A flaw was found in Erlang OTP (inets modules). A remote unauthenticated attacker could exploit an incorrect authorization vulnerability when CGI (Common Gateway Interface) scripts are served via script_alias. This vulnerability arises from a path mismatch where access controls are evaluated against a different path than the script's execution path. This allows unauthorized access to CGI scripts intended to be protected by directory rules, potentially leading to information disclosure or the execution of unauthorized scripts.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
