Use of Externally-Controlled Format String

In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure.Show less

Format String vulnerability in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition or execute arbitrary code with elevated privileges on an affected device. Cisco Bug IDs: CSCvd73664.Show less

A cross-protocol scripting issue was discovered in the management interface in OpenVPN through 2.4.5. When this interface is enabled over TCP without a password, and when no other clients are connected to this interface, attackers can execute arbitrary management commands, obtain sensitive information, or cause a denial of service (SIGTERM) by triggering XMLHttpRequest actions in a web browser. This is demonstrated by a multipart/form-data POST to http://localhost:23000 with a "signal SIGTERM" command in a TEXTAREA element. NOTE: The vendor disputes that this is a vulnerability. They state that this is the result of improper configuration of the OpenVPN instance rather than an intrinsic vulnerability, and now more explicitly warn against such configurations in both the management-interface documentation, and with a runtime warningShow less

fmtlib version prior to version 4.1.0 (before commit 0555cea5fc0bf890afe0071a558e44625a34ba85) contains a Memory corruption (SIGSEGV), CWE-134 vulnerability in fmt::print() library function that can result in Denial of Service. This attack appear to be exploitable via Specifying an invalid format specifier in the fmt::print() function results in a SIGSEGV (memory corruption, invalid write). This vulnerability appears to have been fixed in after commit 8cf30aa2be256eba07bb1cefb998c52326e846e7.Show less

Puppet Enterprise 2017.3.x prior to 2017.3.3 are vulnerable to a remote execution bug when a specially crafted string was passed into the facter_task or puppet_conf tasks. This vulnerability only affects tasks in the affected modules, if you are not using puppet tasks you are not affected by this vulnerability.Show less

This 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.Show less

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Netgain Enterprise Manager. Authentication is not required to exploit this vulnerability. The specific flaw exists within exec.jsp. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code under the context of the current user. Was ZDI-CAN-4749.Show less

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of NetGain Systems Enterprise Manager 7.2.730 build 1034. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the org.apache.jsp.u.jsp.tools.exec_jsp servlet, which listens on TCP port 8081 by default. When parsing the command parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code under the context of Administrator. Was ZDI-CAN-5193.Show less

Open On-Chip Debugger (OpenOCD) 0.10.0 does not block attempts to use HTTP POST for sending data to 127.0.0.1 port 4444, which allows remote attackers to conduct cross-protocol scripting attacks, and consequently execute arbitrary commands, via a crafted web site.Show less

In the yajl-ruby gem 1.3.0 for Ruby, when a crafted JSON file is supplied to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in the yajl_string_decode function in yajl_encode.c. This results in the whole ruby process terminating and potentially a denial of service.Show less

ovirt_safe_delete_config in ovirtfunctions.py and other unspecified locations in ovirt-node 3.0.0-474-gb852fd7 as packaged in Red Hat Enterprise Virtualization 3 do not properly quote input strings, which allows remote authenticated users and physically proximate attackers to execute arbitrary commands via a ; (semicolon) in an input string.Show less

Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap memory corruption or an information disclosure from the heap.Show less
