Huawei HG532 routers, including the HG532e, n, s, and possibly other models, are vulnerable to arbitrary file access through path traversal.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’) - CVE-2015-7254
In vulnerable Huawei router models, the /icon/ path of requests to Internet-facing TCP port 37215 can be manipulated to gain access to arbitrary files. For instance, a remote, unauthenticated attacker could read the inittab
file by directly requesting http://<target_IP>:37215/icon/../../../etc/inittab
.
A LAN-based attacker can access arbitrary files on vulnerable devices. Note that in some configurations, an external attacker may be able to leverage this vulnerability.
