Two critical vulnerabilities have been found recently in the wireless LAN devices of Contec. These critical vulnerabilities were discovered by the cybersecurity analysts, Samy Younsi and Thomas Knudsen of Necrum Security Lab.
There are two models of the FLEXLAN FXA2000 and FXA3000 series from CONTEC which are primarily used in airplane installations as WiFi access points.
As a result, these devices offer extremely high-speed connectivity during flight trips for the following purposes:-
Researchers from JFrog’s Security Research team discovered five vulnerabilities in the popular PJSIP open-source multimedia communication library.
PJSIP is a communication library written in C language implementing standard-based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. It combines signaling protocol (SIP) with rich multimedia framework and NAT traversal functionality into high level API that is portable and suitable for almost any type of systems ranging from desktops, embedded systems, to mobile handsets.
PJSIP supports audio, video, presence, and instant messaging, the APT supplied by the library can be used by IP telephony applications, including VoIP devices.
Many popular communication applications use the library, including WhatsApp, BlueJeans and Asterisk.
An attacker can exploit the flaws to gain arbitrary code execution on devices running applications using the vulnerable library or to trigger a denial-of-service (DoS) condition.
