One of the SQL injection vulnerabilities that affects Unified CM IM&P also affects Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) and could allow an attacker to conduct SQL injection attacks on an affected system. For more information about these vulnerabilities, see the Details section of this advisory. 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-imp-trav-inj-dM687ZD6 Affected Products o Vulnerable Products At the time of publication, these vulnerabilities affected the following Cisco products: Unified CM Unified CM IM&P Unified CM SME For information about which Cisco software releases are vulnerable, see the Fixed Software section of this advisory. See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information. Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by these vulnerabilities. Details o The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities. Details about the vulnerabilities are as follows. CVE-2021-1357: Cisco Unified Communications Manager IM & Presence Service Path Traversal Vulnerability A vulnerability in the web-based management interface of Cisco Unified CM IM&P could allow an authenticated, remote attacker to conduct path traversal attacks and obtain read access to sensitive files on an affected system. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to read files on the underlying operating system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvv20985 CVE ID: CVE-2021-1357 Security Impact Rating (SIR): Medium CVSS Base Score: 6.5 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N CVE-2021-1355: Cisco Unified Communications Manager IM & Presence Service SQL Injection Vulnerability A vulnerability in the web-based management interface of Cisco Unified CM IM&P could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. The vulnerability is due to improper validation of user-submitted parameters. An attacker could exploit this vulnerability by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain data that is stored in the underlying database, including hashed user credentials. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvv20974 CVE ID: CVE-2021-1355 Security Impact Rating (SIR): Medium CVSS Base Score: 6.5 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N CVE-2021-1364: Cisco Unified Communications Manager IM & Presence Service SQL Injection Vulnerability A vulnerability in the web-based management interface of Cisco Unified CM IM&P could allow an authenticated, remote attacker with administrative credentials to conduct SQL injection attacks on an affected system. The vulnerability is due to improper validation of user-submitted parameters. An attacker could exploit this vulnerability by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain data that is stored in the underlying database. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvv62648 CVE ID: CVE-2021-1364 Security Impact Rating (SIR): Medium CVSS Base Score: 4.9 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N CVE-2021-1282: Cisco Unified Communications Manager SQL Injection Vulnerability A vulnerability in the web-based management interface of Cisco Unified CM and Cisco Unified CM SME could allow an authenticated, remote attacker with administrative credentials to conduct SQL injection attacks on an affected system. The vulnerability is due to improper validation of user-submitted parameters. An attacker could exploit this vulnerability by authenticating to the application and sending malicious requests to an affected system. A successful exploit could allow the attacker to obtain data that is stored in the underlying database. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. Bug ID(s): CSCvv62642 CVE ID: CVE-2021-1364 Security Impact Rating (SIR): Medium CVSS Base Score: 4.9 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N Workarounds o There are no workarounds that address these vulnerabilities. Fixed Software o 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.
