Juniper Networks has shipped security patches to cover numerous vulnerabilities across its product portfolio, including a series of critical bugs in third-party software used in the company’s products.
The most important of the vulnerabilities is CVE-2021-0276 (CVSS score of 9.8), a stack-based buffer overflow in Juniper Networks SBR Carrier with EAP. An attacker could exploit it by sending specific packets to cause a denial of service condition or to execute code remotely, Juniper warned in an advisory.
“By continuously sending these specific packets, an attacker can repeatedly crash the radius daemon, causing a sustained Denial of Service (DoS),” the company said.
Juniper Networks SBR Carrier 8.4.1 versions prior to 8.4.1R19; 8.5.0 versions prior to 8.5.0R10; and 8.6.0 versions prior to 8.6.0R4 are impacted if EAP authentication is configured and if Enhanced EAP Logging and TraceLevel setting of 2 are in use.
Juniper Networks also released patches for high-severity vulnerabilities in Junos OS and Junos OS Evolved (EVO) that could lead to Denial of Service (DoS), remote code execution (RCE), local privilege escalation, or traffic loss. Several medium-severity security holes were also addressed in Junos OS and Junos OS Evolved.
Additionally, Juniper Networks published several advisories to announce the release of fixes for multiple vulnerabilities that affect third party software used in its products.
The most important of these is a patch for Junos Space that addresses CVE-2020-1472, a critical (CVSS score of 10) vulnerability in the Netlogon Remote Protocol (MS-NRPC) that Microsoft patched in August 2020. Junos Space 21.2R1 patches this bug and 34 other vulnerabilities, including another critical flaw, several high-severity issues, and multiple medium-risk ones.
By updating third party software, Juniper Networks also patched critical vulnerabilities in Juniper Contrail Insights, CTPView, and Contrail Networking, as well as high-severity bugs in Secure Analytics, Junos OS, and Junos OS Evolved. Multiple other lower severity flaws were also addressed in these products.
