Quick assessment
Affected
OpenIdentityPlatform OpenAM
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.
Open Access Management（OpenAM）是一种访问管理解决方案。在 16.1.1 之前的版本中，MSISDN 认证模块中的 MSISDN 验证（MSISDNValidation）会将请求中提供的 MSISDN 值直接拼接到 LDAP 搜索过滤器中，而没有进行转义处理；同时，默认的空可信网关列表允许所有流量通过。在启用 MSISDN 模块且该模块位于可访问认证链中的域中，未经身份验证的远程攻击者可以注入 LDAP 过滤器的元字符，从而选择任意匹配的用户，并在无需密码的情况下获得一个普通的已认证 O

Vulnerability Title
OpenAM Authentication Bypass via MSISDN LDAP Injection
Source: CVE Program / CVE List V5
Vulnerability Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, MSISDNValidation in the MSISDN authentication module concatenates the request-supplied MSISDN value into an LDAP search filter without escaping, while the default empty trusted-gateway list allows all traffic. In a realm where an MSISDN module is enabled in a reachable authentication chain, an unauthenticated remote attacker can inject LDAP filter metacharacters, select an arbitrary matching user, and obtain a normal authenticated OpenAM session without a password. This issue is fixed in version 16.1.1.
