GHSA-3X92-JHWW-8QJ8
Vulnerability from github – Published: 2022-05-13 01:37 – Updated: 2022-05-13 01:37This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of NetGain Systems Enterprise Manager v7.2.699 build 1001. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the content parameter provided to the script_test.jsp endpoint. A crafted content request parameter can trigger execution of a system call composed from a user-supplied string. An attacker can leverage this vulnerability to execute code under the context of the web service. Was ZDI-CAN-5080.

GHSA-4GMJ-9M2M-6H5F
Vulnerability from github – Published: 2026-06-12 00:31 – Updated: 2026-06-16 15:33An authenticated format string vulnerability exists in the ONVIF service of Tapo C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as a format string, which can be used to manipulate stack memory, including control flow data such as return addresses.
A remote authenticated attacker may redirect execution flow to existing internal functions, triggering an unauthorized factory reset, leading to loss of configuration, deletion of stored credentials and service disruption.

Mitigation
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.
