GHSA-GQVF-FXMV-5GJ9
Vulnerability from github – Published: 2023-06-07 09:30 – Updated: 2024-04-04 04:39On Triangle MicroWorks' SCADA Data Gateway version <= v5.01.03, an unauthenticated attacker can send a specially crafted broadcast message including format string characters to the SCADA Data Gateway to perform unrestricted memory reads.An unauthenticated user can use this format string vulnerability to repeatedly crash the GTWWebMonitor.exe process to DoS the Web Monitor. Furthermore, an authenticated user can leverage this vulnerability to leak memory from the GTWWebMonitor.exe process. This could be leveraged in an exploit chain to gain code execution.

Vulnerability from github – Published: 2024-06-19 00:31 – Updated: 2024-06-19 00:31Actiontec WCB6200Q Cookie Format String Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Actiontec WCB6200Q routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the HTTP server. A crafted Cookie header in an HTTP request can trigger the use of a format specifier from a user-supplied string. An attacker can leverage this vulnerability to execute code in the context of the HTTP server. Was ZDI-CAN-21417.

Vulnerability from github – Published: 2022-05-13 01:22 – Updated: 2022-05-13 01:22An issue was discovered in handler_ipcom_shell_pwd in the Interpeak IPCOMShell TELNET server on Green Hills INTEGRITY RTOS 5.0.4. When using the pwd command, the current working directory path is used as the first argument to printf() without a proper check. An attacker may thus forge a path containing format string modifiers to get a custom format string evaluated. This results in an information leak of memory addresses.

Choose a language that is not subject to this flaw.
Mitigation
Ensure that all format string functions are passed a static string which cannot be controlled by the user, and that the proper number of arguments are always sent to that function as well. If at all possible, use functions that do not support the %n operator in format strings. [REF-116] [REF-117]
Mitigation
Run compilers and linkers with high warning levels, since they may detect incorrect usage.
CAPEC-135: Format String Injection
An adversary 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 adversary 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 adversary can write to the program stack.
CAPEC-67: String Format Overflow in syslog()
This attack targets applications and software that uses the syslog() function insecurely. If an application does not explicitely use a format string parameter in a call to syslog(), user input can be placed in the format string parameter leading to a format string injection attack. Adversaries can then inject malicious format string commands into the function call leading to a buffer overflow. There are many reported software vulnerabilities with the root cause being a misuse of the syslog() function.
