Security Vulnerabilities - CVEs Published In July 2021
Due to the Asset Explorer agent not validating HTTPS certificates, an attacker on the network can statically configure their IP address to match the Asset Explorer's Server IP address. This will allow an attacker to send a NEWSCAN request to a listening agent on the network as well as receive the agent's HTTP request verifying its authtoken. In AEAgent.cpp, the agent responding back over HTTP is vulnerable to a Heap Overflow if the POST payload response is too large. The POST payload response is converted to Unicode using vswprintf. This is written to a buffer only 0x2000 bytes big. If POST payload is larger, then heap overflow will occur.

Due to Manage Engine Asset Explorer Agent 1.0.34 not validating HTTPS certificates, an attacker on the network can statically configure their IP address to match the Asset Explorer's Server IP address. This will allow an attacker to send a NEWSCAN request to a listening agent on the network as well as receive the agent's HTTP request verifying its authtoken. In httphandler.cpp, the agent reaching out over HTTP is vulnerable to an Integer Overflow, which can be turned into a Heap Overflow allowing for remote code execution as NT AUTHORITY/SYSTEM on the agent machine. The Integer Overflow occurs when receiving POST response from the Manage Engine server, and the agent calling "HttpQueryInfoW" in order to get the "Content-Length" size from the incoming POST request. This size is taken, but multiplied to a larger amount. If an attacker specifies a Content-Length size of 1073741823 or larger, this integer arithmetic will wrap the value back around to smaller integer, then calls "calloc" with this size to allocate memory. The following API "InternetReadFile" will copy the POST data into this buffer, which will be too small for the contents, and cause heap overflow.

The Lexmark Universal Print Driver version 2.15.1.0 and below, G2 driver 2.7.1.0 and below, G3 driver 3.2.0.0 and below, and G4 driver 4.2.1.0 and below are affected by a privilege escalation vulnerability. A standard low priviliged user can use the driver to execute a DLL of their choosing during the add printer process, resulting in escalation of privileges to SYSTEM.

Siren Investigate before 11.1.1 contains a server side request forgery (SSRF) defect in the built-in image proxy route (which is enabled by default). An attacker with access to the Investigate installation can specify an arbitrary URL in the parameters of the image proxy route and fetch external URLs as the Investigate process on the host.
