==================================================================== CERT-Renater Note d'Information No. 2020/VULN463 _____________________________________________________________________ DATE : 20/08/2020 HARDWARE PLATFORM(S): Cisco Video Surveillance 8000 Series IP Cameras. OPERATING SYSTEM(S): Cisco Video Surveillance 8000 Series IP Camera Firmware versions prior to 1.0.9-4. ===================================================================== https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipcameras-rce-dos-uPyJYxN3 _____________________________________________________________________ Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Remote Code Execution and Denial of Service Vulnerabilities High Advisory ID: cisco-sa-ipcameras-rce-dos-uPyJYxN3 First Published: 2020 August 19 16:00 GMT Version 1.0: Final Workarounds: No workarounds available Cisco Bug IDs: CSCvu82728 CSCvu82729 CVSS Score: Base 8.8 CVE-2020-3506 CVE-2020-3507 CWE-20 Summary Multiple vulnerabilities in the Cisco Discovery Protocol implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP camera. These vulnerabilities are due to missing checks when the IP cameras process a Cisco Discovery Protocol packet. An attacker could exploit these vulnerabilities by sending a malicious Cisco Discovery Protocol packet to the targeted IP camera. A successful exploit could allow the attacker to execute code on the affected IP camera or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipcameras-rce-dos-uPyJYxN3 Affected Products Vulnerable Products These vulnerabilities affect Cisco Video Surveillance 8000 Series IP Cameras if they are running a firmware version earlier than 1.0.9-4 and have the Cisco Discovery Protocol enabled. Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by these vulnerabilities. Cisco has confirmed that these vulnerabilities do not affect the following Cisco products: Video Surveillance 3000 Series IP Cameras Video Surveillance 4000 Series High-Definition IP Cameras Video Surveillance 4300E and 4500E High-Definition IP Cameras Video Surveillance 6000 Series IP Cameras Video Surveillance 7000 Series IP Cameras Video Surveillance PTZ IP Cameras Workarounds There are no workarounds that address these vulnerabilities. Fixed Software Cisco has released free software updates that address the vulnerabilities described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/end-user-license-agreement.html Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Fixed Releases Cisco fixed these vulnerabilities in Cisco Video Surveillance 8000 Series IP Camera Firmware releases 1.0.9-4 and later.
