Cybersecurity researchers have thorough as several as 5 critical security flaws in the implementation of TLS protocol in various designs of Aruba and Avaya network switches that could be abused to acquire distant access to enterprise networks and steal beneficial info.
The conclusions follow the March disclosure of TLStorm, a established of 3 critical flaws in APC Smart-UPS gadgets that could allow an attacker to just take in excess of regulate and, even worse, bodily harm the appliances.
IoT security firm Armis, which uncovered the shortcomings, observed that the style flaws can be traced back again to a typical resource: a misuse of NanoSSL, a expectations-centered SSL developer suite from Mocana, a DigiCert subsidiary.
The new established of flaws, dubbed TLStorm 2., renders Aruba and Avaya network switches vulnerable to distant code execution vulnerabilities, enabling an adversary to commandeer the devices, shift laterally across the network, and exfiltrate delicate knowledge.
Afflicted products include Avaya ERS3500 Series, ERS3600 Series, ERS4900 Series, and ERS5900 Series as properly as Aruba 5400R Collection, 3810 Sequence, 2920 Sequence, 2930F Series, 2930M Sequence, 2530 Collection, and 2540 Series.
Armis chalked up the flaws to an “edge scenario,” a failure to adhere to guidelines pertaining to the NanoSSL library that could result in distant code execution. The list of distant code execution bugs is as follows –
- CVE-2022-23676 (CVSS score: 9.1) – Two memory corruption vulnerabilities in the RADIUS client implementation of Aruba switches
- CVE-2022-23677 (CVSS score: 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 Submit request dealing with heap overflow vulnerability in a discontinued Avaya merchandise line (no CVE)
“These investigate conclusions are substantial as they emphasize that the network infrastructure alone is at risk and exploitable by attackers, meaning that network segmentation alone is no lengthier sufficient as a security evaluate,” Barak Hadad, head of investigate in engineering at Armis, claimed.
Businesses deploying impacted Avaya and Aruba gadgets are highly suggested to implement the patches to mitigate any probable exploit tries.
