Using a crafted request an attacker is able to modify certain PHP environment variables, leading to partial loss of integrity, which may allow chaining to other vulnerabilities.Thu, 03 Sep 2026 00:00:00 GMTJunipermediumcvehttps://0daynews.com/cve/cve-2023-36845/https://0daynews.com/cve/cve-2023-36845/Juniper Junos OS on EX Series and SRX Series contains a PHP external variable modification vulnerability that allows an unauthenticated, network-based attacker to control an important environment variable. Using a crafted request, which sets the variable PHPRC, an attacker is able to modify the PHP execution environment allowing the injection und execution of code.Thu, 03 Sep 2026 00:00:00 GMTJunipercriticalcvehttps://0daynews.com/cve/cve-2023-36846/https://0daynews.com/cve/cve-2023-36846/Juniper Junos OS on SRX Series contains a missing authentication for critical function vulnerability that allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity. With a specific request to user.php that doesn't require authentication, an attacker is able to upload arbitrary files via J-Web, leading to a loss of integrity for a certain part of the file system, which may allow chaining to other vulnerabilities.Thu, 03 Sep 2026 00:00:00 GMTJunipermediumcvehttps://0daynews.com/cve/cve-2023-36847/https://0daynews.com/cve/cve-2023-36847/Juniper Junos OS on EX Series contains a missing authentication for critical function vulnerability that allows an unauthenticated, network-based attacker to cause limited impact to the file system integrity.
