# Summary .be TEMP folder is vulnerable to DLL redirection attacks that allow the attacker to escalate privileges. # Details If the bundle is not run as admin, the user's TEMP folder is used and not the system TEMP folder. A utility is able to monitor the user's TEMP folder for changes and drop its own DLL into the .be/.Local folder immediately when the .be folder is created. When the burn engine elevates, the malicious DLL receives elevated privileges. # PoC As a standard, non-admin user: 1. Monitor the user's TEMP folder for changes using ReadDirectoryChangesW 1. On FILE_ACTION_ADDED, check if the folder name is .be 1. Create a folder in .be named after the bundle + .Local (e.g. MyInstaller.exe.Local) 1. Put the malicious COMCTL32.DLL in the .Local folder following the naming used for the real DLL (e.g. MyInstaller.exe.Local/x86_microsoft.windows.common-controls_.../COMCTL32.dll) 1. Do hacker things when the engine escalates and the malicious DLL is loaded Proper naming f...
Uncovered issues fall into use-after-free, buffer-overflow, information leak and denial of service vulnerability classes. Some of these could be combined to achieve remote code execution or privilege escalation.

A WIRED analysis of leaked police documents verifies that a secretive government program is allowing federal, state, and local law enforcement to access phone records of Americans who are not suspected of a crime.
An incomplete permission check on entries in Devolutions Remote Desktop Manager before 2021.2.16 allows attackers to bypass permissions via batch custom PowerShell.
### Summary Graylog utilises only one single source port for DNS queries. ### Details Graylog seems to bind a single socket for outgoing DNS queries. That socket is bound to a random port number which is not changed again. This goes against recommended practice since 2008, when Dan Kaminsky discovered how easy is to carry out DNS cache poisoning attacks. In order to prevent cache poisoning with spoofed DNS responses, it is necessary to maximise the uncertainty in the choice of a source port for a DNS query. ### PoC The attached figure shows the source ports distribution difference between Graylog configured to use a data adapter based on DNS queries and ISC Bind. The source port distribution of the DNS queries sent from Graylog to a recursive DNS name server running Bind (CLIENT_QUERY) are depicted in purple, while the queries sent from the recursive DNS server to the authoritatives (RESOLVER_QUERY) are plotted in green color. As it can be observed, in contrast to ISC Bind which ...
### Summary The function `lookupPreprocess()` is meant to apply some transformations to a string by disabling characters in the regex `[-_ .]`. However, due to the use of late Unicode normalization of type NFKD, it is possible to bypass that validation and re-introduce all the characters in the regex `[-_ .]`. ```go // lookupPreprocess applies transformations to s so that it can be compared // to search for something. // For example, it is used by (ThemeStore).Lookup func lookupPreprocess(s string) string { return strings.ToLower(norm.NFKD.String(regexp.MustCompile(`[-_ .]`).ReplaceAllString(s, ""))) } ``` Take the following equivalent Unicode character U+2024 (․). Initially, the `lookupPreprocess()` function would compile the regex and replace the regular dot (.). However, the U+2024 (․) would bypass the `ReplaceAllString()`. When the normalization operation is applied to U+2024 (․), the resulting character will be U+002E (.). Thus, the dot was reintroduced back. ### Impact The...
