Juniper Networks' Steel-Belted Radius (SBR) Carrier Edition has a severe remote code-execution vulnerability that leaves wireless carrier and fixed operator networks vulnerable to tampering. By centralizing user authentication, giving the proper level of access, and verifying compliance with security standards, telecom carriers utilize the SBR Carrier server to manage policies for how subscribers use their networks. It enables carriers to distinguish service tiers, diversify revenue models, and manage network resources. Juniper Networks, Inc. is a multinational technology company based in Sunnyvale, California. Routers, switches, network management software, network security solutions, and software-defined networking technology are among the networking products developed and sold by the company. Pradeep Sindhu started the company in 1996, with Scott Kriens serving as the original CEO until September 2008. Juniper Networks began by specializing in core routers, which are used by internet service providers (ISPs) to execute IP address lookups and route internet traffic. SBR Carrier versions 8.4.1, 8.5.0, and 8.6.0 that use the extensible authentication protocol are affected by the bug (CVE-2021-0276). It was on Wednesday, Juniper released a patch. On the CVSS vulnerability-severity rating scale, it gets a 9.8 out of 10. According to Juniper's advisory, it's a stack-based buffer-overflow vulnerability that an attacker can exploit by sending specially designed packets to the platform, causing the RADIUS daemon to crash. This can cause RCE as well as denial-of-service (DoS), which prevents phone subscribers from having a network connection. The flaw is one of the dozens that the networking giant patched this week across its carrier and corporate product lines, including multiple high-severity flaws that could be used to launch DoS assaults. Juniper claims that one of these can also be used for RCE. CVE-2021-0277 is an out-of-bounds read ..
