Exploitation

Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Kamailio 6.1.3 和 6.1.4 版本的 ims_qos_npn 模块中存在基于栈的缓冲区溢出漏洞。w_rx_aar_register() 函数在未验证长度的情况下，将攻击者控制的 SIP 头域中的主机字段复制到固定长度为 46 字节的栈缓冲区中。未经认证的远程攻击者可通过构造特制的 SIP 请求触发该漏洞，导致栈损坏并终止受影响的 Kamailio 实例，从而引发拒绝服务（DoS）。

Vulnerability Description
A stack-based buffer overflow exists in Kamailio v6.1.3 and v6.1.4 in the ims_qos_npn module. The w_rx_aar_register() function copies the attacker-controlled host field from the SIP `Via` header into a fixed 46-byte stack buffer without validating its length. An unauthenticated remote attacker can trigger the vulnerability with a crafted SIP `REGISTER` request, causing stack corruption and termination of the affected Kamailio instance, resulting in denial of service.
