Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging/Manipulating Configuration File Search Paths
    This attack loads a malicious resource into a program's standard path used to bootstrap and/or provide contextual information for a program like a path variable or classpath. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker. A standard UNIX path looks similar to this If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf: This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution.

    descriptionThe remote host is running a version of macOS or Mac OS X that is 10.15.x prior to 10.15.1, 10.14.x prior to 10.14.6 security update 2019-001, 10.13.x prior to 10.13.6 security update 2019-006. It is, therefore, affected by multiple vulnerabilities : - An out-of-bounds read error exists in the accounts component due to improper input validation. A remote attacker can exploit this, to disclose memory contents. (CVE-2019-8787) - A security bypass vulnerability exists in the App Store component due to an improper state management implementation. A local attacker can exploit this, to login to the account of a previously logged in user without valid credentials. (CVE-2019-8803) - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local attacker can exploit this, to cause unexpected system termination or to read kernel memory. (CVE-2019-8759) Note that Nessus has not tested for this issue but has instead relied only on the operating system
