All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by improper authorization vulnerability. Since appviahttp service has no authorization delay, an attacker can be allowed to brute force account credentials.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by null pointer dereference vulnerability, which may allows an attacker to cause a denial of service via appviahttp service.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by improper access control vulnerability, which may allows an unauthorized user to perform unauthorized operations on the router.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by heap-based buffer overflow vulnerability, which may allow an attacker to execute arbitrary code.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by information exposure vulnerability, which may allow an unauthenticated attacker to get the GPON SN information via appviahttp service.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by command injection vulnerability. Due to insufficient parameter validation check, an authorized user can exploit this vulnerability to take control of user router system.

All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by cross-site scripting vulnerability (XSS). Due to incomplete input validation, an authorized user can exploit this vulnerability to execute malicious scripts.

Some ZTE devices have input verification vulnerabilities. The devices support configuring a static prefix through the web management page. The restriction of the front-end code can be bypassed by constructing a POST request message and sending the request to the creation of a static routing rule configuration interface. The WEB service backend fails to effectively verify the abnormal input. As a result, the attacker can successfully use the vulnerability to tamper parameter values. This affects: ZXHN Z500 V1.0.0.2B1.1000 and ZXHN F670L V1.1.10P1N2E. This is fixed in ZXHN Z500 V1.0.1.1B1.1000 and ZXHN F670L V1.1.10P2N2.
