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. | Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. | Due date: 2023-11-17 | Known ransomware campaign use (KEV): Unknown | Notes (KEV): https://supportportal.juniper.net/s/article/2023-08-Out-of-Cycle-Security-Bulletin-Junos-OS-SRX-Series-and-EX-Series-Multiple-vulnerabilities-in-J-Web-can-be-combined-to-allow-a-preAuth-Remote-Code-Execution?language=en_US ;  https://nvd.nist.gov/vuln/detail/CVE-2023-36846"}, "evidence": [{"type": "vendor_report", "source": "cisa-kev", "signal": "successful_exploitation", "confidence": 0.8, "details": {"cwes": ["CWE-306"], "feed": "CISA Known Exploited Vulnerabilities Catalog", "product": "Junos OS", "due_date": "2023-11-17", "date_added": "2023-11-13", "vendorProject": "Juniper", "vulnerabilityName": "Juniper Junos OS SRX Series Missing Authentication for Critical Function Vulnerability", "knownRansomwareCampaignUse": "Unknown"}}], "references": [{"id": "CVE-2023-36846", "url": "https://www.cisa.gov/known-exploited-vulnerabilities-catalog?search_api_fulltext=CVE-2023-36846"}]}
