CVE-2022-20680 - Improper Privilege Management

Severity

65%

Complexity

27%

Confidentiality

60%

A vulnerability in the web-based management interface of Cisco Prime Service Catalog could allow an authenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to improper enforcement of Administrator privilege levels for low-value sensitive data. An attacker with read-only Administrator access to the web-based management interface could exploit this vulnerability by sending a malicious HTTP request to the page that contains the sensitive data. A successful exploit could allow the attacker to collect sensitive information about users of the system and orders that have been placed using the application.

CVSS 3.1 Base Score 6.5. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

CVSS 2.0 Base Score 4. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N).

Demo Examples

Improper Privilege Management

CWE-269

This code temporarily raises the program's privileges to allow creation of a new user folder.


               
return True
return False#avoid CWE-22 and CWE-78
lowerPrivileges()
return False

While the program only raises its privilege level to create the folder and immediately lowers it again, if the call to os.mkdir() throws an exception, the call to lowerPrivileges() will not occur. As a result, the program is indefinitely operating in a raised privilege state, possibly allowing further exploitation to occur.

Improper Privilege Management

CWE-269

Evidence of privilege change:


               
seteuid(getuid());/* do some stuff */

               
}
// privileged code goes here, for example:// nothing to return

Improper Privilege Management

CWE-269

This code intends to allow only Administrators to print debug information about a system.


               
}
ADMIN,USER,GUEST
}
}
break;
break;
System.out.println("You must be logged in to perform this command");

While the intention was to only allow Administrators to print the debug information, the code as written only excludes those the with the role of "GUEST". Someone with the role of "ADMIN" or "USER" will be allowed access, which goes against the original intent. An attacker may be able to use this debug information to craft an attack on the system.

Improper Privilege Management

CWE-269

This code allows someone with the role of "ADMIN" or "OPERATOR" to reset a user's password. The role of "OPERATOR" is intended to have less privileges than an "ADMIN", but still be able to help users with small issues such as forgotten passwords.


               
}
ADMIN,OPERATOR,USER,GUEST
}
}
}
break;
break;
break;
System.out.println("You must be logged in to perform this command");

This code does not check the role of the user whose password is being reset. It is possible for an Operator to gain Admin privileges by resetting the password of an Admin account and taking control of that account.
