![]() This results in the media session being torn down, which is followed by teardown at signaling (SIP) level too. If an attacker manages to send a ClientHello DTLS message with an invalid CipherSuite (such as `TLS_NULL_WITH_NULL_NULL`) to the port on the FreeSWITCH server that is expecting packets from the caller, a DTLS error is generated. This attack can be done continuously, thus denying new DTLS-SRTP encrypted calls during the attack. Prior to version 1.10.11, when handling DTLS-SRTP for media setup, FreeSWITCH is susceptible to Denial of Service due to a race condition in the hello handshake phase of the DTLS protocol. An OpenVAS port scan on ports 33 allows a malicious remote client to cause a denial of service.įreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.Ī vulnerability was found in MariaDB. VDB-247158 is the identifier assigned to this vulnerability. It appears that insufficient access control is depending on referrer header data. In some cases if access to /assets/ is refused, you may enter /assets/x as a wrong value, then come back to /assets/ which we will show the requested data. If you visited /invoke/wm.server/connect, you'll be able to see details like internal IPs, ports, and versions. ![]() By just clicking CANCEL you will be redirected to the directory. To access a file like /assets/ a popup may request username and password. ![]() It is possible to launch the attack remotely. The manipulation leads to improper access controls. Affected is an unknown function of the file wm.server/connect/. ![]() A vulnerability classified as critical has been found in Software AG WebMethods 10.11.x/10.15.x. ![]()
