Oct 28, 2022
Multiple high-severity security flaws have been disclosed as affecting Juniper Networks devices, some of which could be exploited to achieve code execution. Chief among them is a remote pre-authenticated PHP archive file deserialization vulnerability (CVE-2022-22241, CVSS score: 8.1) in the J-Web component of Junos OS, according to Octagon Networks researcher Paulos Yibelo. "This vulnerability can be exploited by an unauthenticated remote attacker to get remote phar files deserialized, leading to arbitrary file write, which leads to a remote code execution (RCE)," Yibelo said in a report shared with The Hacker News. Also identified are five other issues, which are listed as follow - CVE-2022-22242 (CVSS score: 6.1) - A pre-authenticated reflected XSS on the error page ("error.php"), allowing a remote adversary to siphon Junos OS admin session and chained with other flaws that require authentication. CVE-2022-22243 (CVSS score: 4.3) & CVE-2022-22
