Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

NASL familyMacOS X Local Security Checks
NASL idMACOS_10_12_4.NASL
descriptionThe remote host is running a version of macOS that is 10.12.x prior to 10.12.4. It is, therefore, affected by multiple vulnerabilities in multiple components, some of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these remote code execution vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. The affected components are as follows : - apache - apache_mod_php - AppleGraphicsPowerManagement - AppleRAID - Audio - Bluetooth - Carbon - CoreGraphics - CoreMedia - CoreText - curl - EFI - FinderKit - FontParser - HTTPProtocol - Hypervisor - iBooks - ImageIO - Intel Graphics Driver - IOATAFamily - IOFireWireAVC - IOFireWireFamily - Kernel - Keyboards - libarchive - libc++abi - LibreSSL - MCX Client - Menus - Multi-Touch - OpenSSH - OpenSSL - Printing - python - QuickTime - Security - SecurityFoundation - sudo - System Integrity Protection - tcpdump - tiffutil - WebKit
