Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionTuomas Rasanen discovered two vulnerabilities in unADF, a tool to extract files from an Amiga Disk File dump (.adf) : - CVE-2016-1243 A stack-based buffer overflow in the function extractTree() might allow an attacker, with control on the content of a ADF file, to execute arbitrary code with the privileges of the program execution. - CVE-2016-1244 The unADF extractor creates the path in the destination via a mkdir in a system() call. Since there was no sanitization on the input of the filenames, an attacker can directly inject code in the pathnames of archived directories in an ADF file.

    descriptionIt was discovered that there were two vulnerabilities in unadf, a tool to extract files from an Amiga Disk File dump (.adf) : - CVE-2016-1243: stack-based buffer overflow caused by blindly trusting on pathname lengths of archived files. Stack allocated buffer sysbuf was filled with sprintf() without any bounds checking in extracTree() function. - CVE-2016-1244: execution of unsanitized input Shell command used for creating directory paths was constructed by concatenating names of archived files to the end of the command string.
