CVE-2022-35879 (GCVE-0-2022-35879)

Vulnerability from cvelistv5 – Published: 2022-10-25 16:34 – Updated: 2025-04-15 18:42
VLAI
Summary
Four format string injection vulnerabilities exist in the UPnP logging functionality of Abode Systems, Inc. iota All-In-One Security Kit 6.9Z and 6.9X. A specially-crafted UPnP negotiation can lead to memory corruption, information disclosure, and denial of service. An attacker can host a malicious UPnP service to trigger these vulnerabilities.This vulnerability arises from format string injection via `controlURL` XML tag, as used within the `DoUpdateUPnPbyService` action handler.

CVE-2022-35876 (GCVE-0-2022-35876)

Vulnerability from cvelistv5 – Published: 2022-10-25 16:34 – Updated: 2025-04-15 18:43
VLAI
Summary
Four format string injection vulnerabilities exist in the XCMD testWifiAP functionality of Abode Systems, Inc. iota All-In-One Security Kit 6.9X and 6.9Z. Specially-crafted configuration values can lead to memory corruption, information disclosure and denial of service. An attacker can modify a configuration value and then execute an XCMD to trigger these vulnerabilities.This vulnerability arises from format string injection via the `default_key_id` and `key` configuration parameters, as used within the `testWifiAP` XCMD handler
Severity

Title
Format string vulnerability in AT+CTGL command in Motorola MTM5000
Summary
A format string vulnerability exists in Motorola MTM5000 series firmware AT command handler for the AT+CTGL command. An attacker-controllable string is improperly handled, allowing for a write-anything-anywhere scenario. This can be leveraged to obtain arbitrary code execution inside the teds_app binary, which runs with root privileges.

Mitigation
Requirements

Choose a language that is not subject to this flaw.

Mitigation
Implementation

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
Build and Compilation

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.
