{"id":"CVE-2016-9553","url":"https://www.cyber-defence.io/tools/cve/CVE-2016-9553","generatedAt":"2026-10-28T23:07:53.938Z","title":"The Sophos Web Appliance (version 4.2.1.3) is vulnerable to two Remote Command Injection vulnerabilities affecting its web administrative interface.","description":"The Sophos Web Appliance (version 4.2.1.3) is vulnerable to two Remote Command Injection vulnerabilities affecting its web administrative interface. These vulnerabilities occur in the MgrReport.php (/controllers/MgrReport.php) component responsible for blocking and unblocking IP addresses from accessing the device. The device doesn't properly escape the information passed in the variables 'unblockip' and 'blockip' before calling the shell_exec() function which allows for system commands to be injected into the device. The code erroneously suggests that the information handled is protected by utilizing the variable name 'escapedips' - however this was not the case. The Sophos ID is NSWA-1258.","published":"2017-01-28T12:59:00.000Z","lastModified":"2026-06-17T00:56:12.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.2,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-77"],"affected":["sophos/web appliance"],"epss":{"score":0.19815,"percentile":0.97397,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.16322,"percentile":0.96867},{"date":"2026-09-22","score":0.19462,"percentile":0.97249}]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2016-12-12","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":41413,"kind":"exploit","title":"Sophos Web Appliance 4.2.1.3 - block/unblock Remote Command Injection (Metasploit)","url":"https://www.exploit-db.com/exploits/41413","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/php/webapps/41413.rb","file":"exploits/php/webapps/41413.rb","published":"2016-12-12","added":"2017-02-21","updated":"2017-07-18","author":"xort","type":"webapps","platform":"php","port":null,"verified":true,"codes":["CVE-2016-9553"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 19.8%, higher than 97% of all known CVEs.
