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:NCVE-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.

CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:NCVE-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.

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.
