Critical TLStorm 2.0 Bugs Affect Widely-Used Aruba and Avaya Network Switches

Cybersecurity scientists have comprehensive as several as five extreme security flaws in the implementation of TLS protocol in many models of Aruba and Avaya network switches that could be abused to acquire remote accessibility to business networks and steal valuable info.

The findings stick to the March disclosure of TLStorm, a set of three critical flaws in APC Intelligent-UPS devices that could permit an attacker to take over handle and, even worse, bodily harm the appliances.

IoT security agency Armis, which uncovered the shortcomings, famous that the layout flaws can be traced back again to a prevalent supply: a misuse of NanoSSL, a standards-centered SSL developer suite from Mocana, a DigiCert subsidiary.

The new established of flaws, dubbed TLStorm 2., renders Aruba and Avaya network switches susceptible to distant code execution vulnerabilities, enabling an adversary to commandeer the devices, transfer laterally across the network, and exfiltrate sensitive knowledge.

Impacted equipment incorporate Avaya ERS3500 Series, ERS3600 Series, ERS4900 Sequence, and ERS5900 Collection as properly as Aruba 5400R Sequence, 3810 Sequence, 2920 Series, 2930F Collection, 2930M Sequence, 2530 Sequence, and 2540 Sequence.

Armis chalked up the flaws to an “edge circumstance,” a failure to adhere to guidelines pertaining to the NanoSSL library that could consequence in remote code execution. The listing of remote code execution bugs is as follows –

• CVE-2022-23676 (CVSS rating: 9.1) – Two memory corruption vulnerabilities in the RADIUS shopper implementation of Aruba switches
• CVE-2022-23677 (CVSS rating: 9.) – NanoSSL misuse on several interfaces in Aruba switches
• CVE-2022-29860 (CVSS rating: 9.8) – TLS reassembly heap overflow vulnerability in Avaya switches
• CVE-2022-29861 (CVSS score: 9.8) – HTTP header parsing stack overflow vulnerability in Avaya switches
• HTTP Article ask for dealing with heap overflow vulnerability in a discontinued Avaya solution line (no CVE)

“These exploration results are major as they spotlight that the network infrastructure alone is at risk and exploitable by attackers, this means that network segmentation by itself is no lengthier enough as a security measure,” Barak Hadad, head of investigate in engineering at Armis, explained.

Businesses deploying impacted Avaya and Aruba products are really encouraged to use the patches to mitigate any likely exploit makes an attempt.
