Emanuel Duss from Compass Security reported 2 medium severity security issues in 3CX phone system components:

In the first case, the subject of the advisory explains everything. The Windows (legacy), Android or iOS clients simply do not verify the TLS certificate of the 3CX server. This allows man-in-the-middle attackers to get the provisioning data which would typically include credentials and so on.

As for mitigation, the advisory says:

According to the 3CX, the vulnerability will be tackled in future redesigns of the mobile apps.
Users of the legacy Windows client can switch to the new Electron based 3CX
Desktop App which is not affected.

The second issue has been well known since a few years according to the references to German 3CX forums but does not appear to be addressed yet.

The advisory says that:

There is no security update for this vulnerability at the moment. According to the 3CX, the vulnerability will be tackled in future redesigns of the
management console.

3CX also published a hotfix with the following basic information in their changelog:

Fix for a security vulnerability
Fix of memory leak affecting business systems in particular conditions
Fix for application crash of the call manager if under DDOS attack.

If you use 3CX’s software, do upgrade as we’re told these are high or critical severity vulnerabilities. See their post here: Security & Memory Hotfix Available for V18 Update 3.

Kerbit blog posts about Pascom and VoIPmonitor

Security researchers at Kerbit released two interesting blog posts:

In the case of Pascom’s phone system, they essentially chained three different vulnerabilities to get remote code execution. The first vulnerability was a path traversal in the Nginx proxy. This allowed them to reach any application on a Tomcat server behind Nginx. This in turn, exposed an Openfire (XMPP) server that had an SSRF vulnerability – this being the second vulnerability in the chain. This SSRF issue was then used to reach a localhost web service that exposes a (random) password for the user moby. These credentials could then be used to schedule a task that is executed by a Perl script that runs as root.

The second post is about the VoIPmonitor GUI where they found multiple vulnerabilities, such as authentication bypass, SQL injection and remote code execution.

CVE-2022-26143: Mitel MiCollab and MiVoice Business Express used to launch DDoS attacks

Mitel MiCollab phone system has a vulnerability that may be abused in UDP amplification attacks, i.e. be used to launch DDoS attacks. The impressive thing about this issue is the amplification factor of 220 billion percent.

To abuse this issue, attackers need to find Mitel equipment that runs tp240dvr (“TP-240 driver”) on UDP port 10074 that happens to be exposed to the Internet. Then the attacker needs to be able to send a debugging command startblast from a spoofed IP address which belongs to the target victim organisation. When this is done on a wide scale, attackers get to do bandwidth saturation DDoS attacks for free.

The vulnerable TP-240 driver can also be used for other purposes, such as toll fraud.

This issue was abused in the wild by booter DDoS services which is why it is such a great deal.

More on PJSIP’s vulnerabilities fixed last month

The original reporters from JFrog have now issued technical details about the PJSIP vulnerabilities on their blog: JFrog Discloses 5 Memory Corruption Vulnerabilities in PJSIP – A Popular Multimedia Library

The vulnerabilities are tracked under the following CVEs:

CVE-2021-43299 – Stack overflow in PJSUA API when calling pjsua_player_create
CVE-2021-43300 – Stack overflow in PJSUA API when calling pjsua_recorder_create
CVE-2021-43301 – Stack overflow in PJSUA API when calling pjsua_playlist_create
CVE-2021-43302 – Read out-of-bounds in PJSUA API when calling pjsua_recorder_create
CVE-2021-43303 – Buffer overflow in PJSUA API when calling pjsua_call_dump

It looks like by mentioning 3rd party software such as Asterisk, WhatsApp and BlueJeans, journalists covering this might have assumed that these third-party applications are necessarily vulnerable. In their blog post, the JFrog security team tried to clarify that they did not actually test software that relies on the PJSIP library and only tested the library itself.

Asterisk Advisories

With regards to the multipart issue, the Asterisk developers are not sure if it really a problem but they issued an advisory anyway. Then, the STUN issue is relevant when ICE/WebRTC support is switched on (not default). Finally, the “use after free of dialog set” is marked as a major vulnerability too.
