Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Embedding Scripts within Scripts An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
- Signature Spoofing by Key Theft An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

| description | The Veritas NetBackup installation on the remote Windows host is 7.x prior to version 7.7.2 or is missing a vendor supplied hotfix. It is, therefore, affected by multiple vulnerabilities : - A remote command execution vulnerability exists in the bpcd service due to a failure to properly sanitize user-supplied input. An unauthenticated, remote attacker can exploit this to execute arbitrary commands. (CVE-2015-6550) - An information disclosure vulnerability exists due to insufficient protection of communication between the NBU server and the administration console. A man-in-the-middle attacker can exploit this to disclose sensitive information including login credentials. (CVE-2015-6551) - An unspecified flaw exists that allows a remote attacker to execute arbitrary RPC calls. (CVE-2015-6552) |
