CISCO IOS XE COMMAND PATCH
Command Injection VulnerabilitiesĪ first vulnerability (CVE-2019-12651) with web-based user interface (Web UI) of Cisco IOS XE Software allows low privileged attackers possibly execute the arbitrary command on the vulnerable devices that running with Cisco IOS to elevate privileges.Īnother vulnerability (CVE-2019-12650) that affected the web-based user interface (Web UI) due to improperly sanitizes user-supplied input of Cisco IOS XE Software allows remote attackers to execute commands on the underlying Linux shell of vulnerable devices and gain the root access.Īccording to the Cisco security update, Due to the improperly sanitizes user-supplied input in Cisco IOS, an attacker could exploit this vulnerabilities by supplying a crafted input parameter on a form in the Web UI and then submitting that form.Ĭustomers recommended to disabling the HTTP Server feature eliminates the attack vector for these vulnerabilities until upgrade the system and apply the patch released by Cisco.įollowing command will help to check and shows the output will confirm that it has the HTTP Server feature enabled. This Vulnerable software running Cicso deployed in various Enterprise Networks, data centers, and smaller businesses and the potential attacker exploit the vulnerable devices remotely.Īccording to the Cisco update, These two ( CVE-2019-12650) ( CVE-2019-12651 ) vulnerabilities are not dependent on one another and the attacker no need to exploit one vulnerability to take over another vulnerability.īoth vulnerabilities affected Cisco devices that running vulnerable IOS XE Software release with the HTTP Server feature enabled.
