CWE CWE-284
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 version of Oracle WebLogic Server installed on the remote host is affected by multiple vulnerabilities: - An unspecified vulnerability in the Spring Framework (Sample Apps) subcomponent in Oracle WebLogic allows an unauthenticated, remote attacker to takeover a WebLogic server. (CVE-2018-1275) - An unspecified vulnerability in the WLS Core Components subcomponent in Oracle WebLogic allows an unauthenticated, remote attacker to takeover a WebLogic server. (CVE-2018-2893) - An unspecified vulnerability in the WLS - Web Services subcomponent in Oracle WebLogic allows an unauthenticated, remote attacker with HTTP access to compromise and takeover a WebLogic server. (CVE-2018-2894) In addition, Oracle WebLogic Server is affected by several other lower scoring vulnerabilities in the WLS Core Components, JSF, SAML, and Console (jackson-databind) subcomponents. Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
