HIGH Summary
Pivotal RabbitMQ, versions 3.7.x prior to 3.7.21 and 3.8.x prior to 3.8.1, and RabbitMQ for Pivotal Platform, 1.16.x versions prior to 1.16.7 and 1.17.x versions prior to 1.17.4, contain a web management plugin that is vulnerable to a denial of service attack. The "X-Reason" HTTP Header can be leveraged to insert a malicious Erlang format string that will expand and consume the heap, resulting in the server crashing.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Format String Injection An attacker includes formatting characters in a string input field on the target application. Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An attacker can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the attacker can write to the program stack.
- String Format Overflow in syslog() This attack targets the format string vulnerabilities in the syslog() function. An attacker would typically inject malicious input in the format string parameter of the syslog function. This is a common problem, and many public vulnerabilities and associated exploits have been posted.
