Improper Input Validation

A vulnerability in the CLI of Cisco UCS Central Software could allow an authenticated, local attacker to gain shell access. The vulnerability is due to insufficient input validation of commands entered in the CLI, aka a Restricted Shell Break Vulnerability. An attacker could exploit this vulnerability by entering a specific command with crafted arguments. An exploit could allow the attacker to gain shell access to the underlying system.

A vulnerability in the Cisco FindIT Network Discovery Utility could allow an authenticated, local attacker to perform a DLL preloading attack, potentially causing a partial impact to device availability, confidentiality, and integrity. The vulnerability is due to the application loading a malicious copy of a specific, nondefined DLL file instead of the DLL file it was expecting. An attacker could exploit this vulnerability by placing an affected DLL within the search path of the host system. An exploit could allow the attacker to load a malicious DLL file into the system, thus partially compromising confidentiality, integrity, and availability on the device.

A vulnerability in the HTTP web interface for Cisco Wide Area Application Services (WAAS) could allow an unauthenticated, remote attacker to cause an HTTP Application Optimization (AO) related process to restart, causing a partial denial of service (DoS) condition. The vulnerability is due to lack of input validation of user-supplied input parameters within an HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP request through the targeted device. An exploit could allow the attacker to cause a DoS condition due to a process unexpectedly restarting. The WAAS could drop traffic during the brief time the process is restarting.

A vulnerability in the email message filtering feature of Cisco AsyncOS Software for the Cisco Email Security Appliance could allow an unauthenticated, remote attacker to cause an affected device to run out of memory and stop scanning and forwarding email messages. When system memory is depleted, it can cause the filtering process to crash, resulting in a denial of service (DoS) condition on the device. This vulnerability affects software version 9.0 through the first fixed release of Cisco AsyncOS Software for Cisco Email Security Appliances, both virtual and hardware appliances, if the software is configured to apply a message filter or content filter to incoming email attachments. The vulnerability is not limited to any specific rules or actions for a message filter or content filter. Cisco Bug IDs: CSCvd29354.Show less

A vulnerability in the Operations, Administration, Maintenance, and Provisioning (OAMP) credential reset functionality for Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to gain elevated privileges. The vulnerability is due to a lack of proper input validation. An attacker could exploit this vulnerability by authenticating to the OAMP and sending a crafted HTTP request. A successful exploit could allow the attacker to gain administrator privileges. The attacker must successfully authenticate to the system to exploit this vulnerability. This vulnerability affects Cisco Unified Customer Voice Portal (CVP) running software release 10.5, 11.0, or 11.5. Cisco Bug IDs: CSCve92752.Show less

In Apache Struts 2.3.7 through 2.3.33 and 2.5 through 2.5.12, if an application allows entering a URL in a form field and built-in URLValidator is used, it is possible to prepare a special URL which will be used to overload server process when performing validation of the URL. NOTE: this vulnerability exists because of an incomplete fix for S2-047 / CVE-2017-7672.Show less

The REST Plugin in Apache Struts 2.1.x, 2.3.7 through 2.3.33 and 2.5 through 2.5.12 is using an outdated XStream library which is vulnerable and allow perform a DoS attack using malicious request with specially crafted XML payload.Show less

In Apache Struts 2.5 through 2.5.5, if an application allows entering a URL in a form field and the built-in URLValidator is used, it is possible to prepare a special URL which will be used to overload server process when performing validation of the URL.Show less

An Improper Input Validation issue was discovered in Rockwell Automation MicroLogix 1100 controllers 1763-L16BWA, 1763-L16AWA, 1763-L16BBB, and 1763-L16DWD. A remote, unauthenticated attacker could send a single, specially crafted Programmable Controller Communication Commands (PCCC) packet to the controller that could potentially cause the controller to enter a DoS condition.Show less

GNOME Nautilus before 3.23.90 allows attackers to spoof a file type by using the .desktop file extension, as demonstrated by an attack in which a .desktop file's Name field ends in .pdf but this file's Exec field launches a malicious "sh -c" command. In other words, Nautilus provides no UI indication that a file actually has the potentially unsafe .desktop extension; instead, the UI only shows the .pdf extension. One (slightly) mitigating factor is that an attack requires the .desktop file to have execute permission. The solution is to ask the user to confirm that the file is supposed to be treated as a .desktop file, and then remember the user's answer in the metadata::trusted field.Show less

The admin interface in Landesk Management Suite 9.6 and earlier allows remote attackers to conduct remote file inclusion attacks involving ASPX pages from third-party sites via the d parameter to (1) ldms/sm_actionfrm.asp or (2) remote/frm_coremainfrm.aspx; or the (3) top parameter to remote/frm_splitfrm.aspx.Show less
