Use of Externally-Controlled Format String

It is identified a format string vulnerability in ASUS RT-AX56U V2 & RT-AC86U. This vulnerability is caused by lacking validation for a specific value when calling cm_processChangedConfigMsg in ccm_processREQ_CHANGED_CONFIG function in AiMesh system. An unauthenticated remote attacker can exploit this vulnerability without privilege to perform remote arbitrary code execution, arbitrary system operation or disrupt service. This issue affects RT-AX56U V2: 3.0.0.4.386_50460; RT-AC86U: 3.0.0.4_386_51529.Show less

It is identified a format string vulnerability in ASUS RT-AX56U V2 & RT-AC86U. This vulnerability is caused by directly using input as a format string when calling syslog in logmessage_normal function, in the do_detwan_cgi module of httpd. A remote attacker with administrator privilege can exploit this vulnerability to perform remote arbitrary code execution, arbitrary system operation or disrupt service. This issue affects RT-AX56U V2: 3.0.0.4.386_50460; RT-AC86U: 3.0.0.4_386_51529. Show less

A use of externally-controlled format string in Fortinet FortiOS version 7.2.0 through 7.2.4, FortiOS all versions 7.0, FortiOS all versions 6.4, FortiOS all versions 6.2, FortiProxy version 7.2.0 through 7.2.1, FortiProxy version 7.0.0 through 7.0.7 allows attacker to execute unauthorized code or commands via specially crafted commands.Show less

On 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.Show less

A format string vulnerability in a binary of the Zyxel NBG-418N v2 firmware versions prior to V1.00(AARP.14)C0 could allow a remote authenticated attacker to cause denial-of-service (DoS) conditions on an affected device.Show less

In Git for Windows, the Windows port of Git, no localized messages are shipped with the installer. As a consequence, Git is expected not to localize messages at all, and skips the gettext initialization. However, due to a change in MINGW-packages, the `gettext()` function's implicit initialization no longer uses the runtime prefix but uses the hard-coded path `C:\mingw64\share\locale` to look for localized messages. And since any authenticated user has the permission to create folders in `C:\` (and since `C:\mingw64` does not typically exist), it is possible for low-privilege users to place fake messages in that location where `git.exe` will pick them up in version 2.40.1. This vulnerability is relatively hard to exploit and requires social engineering. For example, a legitimate message at the end of a clone could be maliciously modified to ask the user to direct their web browser to a malicious website, and the user might think that the message comes from Git and is legitimate. It does require local write access by the attacker, though, which makes this attack vector less likely. Version 2.40.1 contains a patch for this issue. Some workarounds are available. Do not work on a Windows machine with shared accounts, or alternatively create a `C:\mingw64` folder and leave it empty. Users who have administrative rights may remove the permission to create folders in `C:\`.Show less

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-1935 1.03 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of ConfigFileUpload requests to the web management portal. The issue results from the lack of proper validation of a user-supplied string before using it as a format specifier. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-16141.Show less

A vulnerability, which was classified as critical, was found in ayttm up to 0.5.0.89. This affects the function http_connect in the library libproxy/proxy.c. The manipulation leads to format string. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The patch is named 40e04680018614a7d2b68566b261b061a0597046. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-222267.Show less

IBM Spectrum Scale (5.1.0.0 through 5.1.2.8 and 5.1.3.0 through 5.1.5.1) and IBM Elastic Storage System (6.1.0.0 through 6.1.2.4 and 6.1.3.0 through 6.1.4.1) could allow an authenticated user to cause a denial of service through the GUI using a format string attack. IBM X-Force ID: 239539.Show less

A format string vulnerability exists in iControl SOAP that allows an authenticated attacker to crash the iControl SOAP CGI process or, potentially execute arbitrary code. In appliance mode BIG-IP, a successful exploit of this vulnerability can allow the attacker to cross a security boundary.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Four format string injection vulnerabilities exist in the web interface /action/wirelessConnect functionality of Abode Systems, Inc. iota All-In-One Security Kit 6.9Z and 6.9X. A specially-crafted HTTP request can lead to memory corruption, information disclosure and denial of service. An attacker can make an authenticated HTTP request to trigger these vulnerabilities.This vulnerability arises from format string injection via the `default_key_id` HTTP parameter, as used within the `/action/wirelessConnect` handler.Show less
