Security Vulnerabilities - CVEs Published In August 2023
A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate requests. An authenticated attacker who could obtain information from a user request within the same realm could use that data to impersonate the victim and generate new session tokens. This issue could impact confidentiality, integrity, and availability.

Connected IO v2.1.0 and prior uses a hard-coded username/password pair embedded in their device's firmware used for device communication using MQTT. An attacker who gained access to these credentials is able to connect to the MQTT broker and send messages on behalf of devices, impersonating them. in order to sign and verify JWT session tokens, allowing attackers to sign arbitrary session tokens and bypass authentication.

matrix-appservice-bridge provides an API for setting up bridges. Starting in version 4.0.0 and prior to versions 8.1.2 and 9.0.1, a malicious Matrix server can use a foreign user's MXID in an OpenID exchange, allowing a bad actor to impersonate users when using the provisioning API. The library does not check that the servername part of the `sub` parameter (containing the user's *claimed* MXID) is the the same as the servername we are talking to. A malicious actor could spin up a server on any given domain, respond with a `sub` parameter according to the user they want to act as and use the resulting token to perform provisioning requests. Versions 8.1.2 and 9.0.1 contain a patch. As a workaround, disable the provisioning API.

PaperCut NG and PaperCut MF before 22.1.3 on Windows allow path traversal, enabling attackers to upload, read, or delete arbitrary files. This leads to remote code execution when external device integration is enabled (a very common configuration).

twitch-tui provides Twitch chat in a terminal. Prior to version 2.4.1, the connection is not using TLS for communication. In the configuration of the irc connection, the software disables TLS, which makes all communication to Twitch IRC servers unencrypted. As a result, communication, including auth tokens, can be sniffed. Version 2.4.1 has a patch for this issue.

Logistics Pipes is a modification (a.k.a. mod) for the computer game Minecraft Java Edition. The mod used Java's `ObjectInputStream#readObject` on untrusted data coming from clients or servers over the network resulting in possible remote code execution when sending specifically crafted network packets after connecting. The affected versions were released between 2013 and 2016 and the issue (back then unknown) was fixed in 2016 by a refactoring of the network IO code.
The issue is present in all Logistics Pipes versions ranged from 0.7.0.91 prior to 0.10.0.71, which were downloaded from different platforms summing up to multi-million downloads. For Minecraft version 1.7.10 the issue was fixed in build 0.10.0.71. Everybody on Minecraft 1.7.10 should check their version number of Logistics Pipes in their modlist and update, if the version number is smaller than 0.10.0.71. Any newer supported Minecraft version (like 1.12.2) never had a Logistics Pipes version with vulnerable code. The best available workaround for vulnerable versions is to play in singleplayer only or update to newer Minecraft versions and modpacks.

matrix-appservice-irc is a Node.js IRC bridge for Matrix. Prior to version 1.0.1, it is possible to craft a command with newlines which would not be properly parsed. This would mean you could pass a string of commands as a channel name, which would then be run by the IRC bridge bot. Versions 1.0.1 and above are patched. There are no robust workarounds to the bug. One may disable dynamic channels in the config to disable the most common execution method but others may exist.

HedgeDoc is software for creating real-time collaborative markdown notes. Prior to version 1.9.9, the API of HedgeDoc 1 can be used to create notes with an alias matching the ID of existing notes. The affected existing note can then not be accessed anymore and is effectively hidden by the new one.
When the freeURL feature is enabled (by setting the `allowFreeURL` config option or the `CMD_ALLOW_FREEURL` environment variable to `true`), any user with the appropriate permissions can create a note by making a POST request to the `/new/<ALIAS>` API endpoint. The `<ALIAS>` parameter can be set to the ID of an existing note. HedgeDoc did not verify whether the provided `<ALIAS>` value corresponds to a valid ID of an existing note and always allowed creation of the new note. When a visitor tried to access the existing note, HedgeDoc will first search for a note with a matching alias before it searches using the ID, therefore only the new note can be accessed.
Depending on the permission settings of the HedgeDoc instance, the issue can be exploited only by logged-in users or by all (including non-logged-in) users. The exploit requires knowledge of the ID of the target note. Attackers could use this issue to present a manipulated copy of the original note to the user, e.g. by replacing the links with malicious ones. Attackers can also use this issue to prevent access to the original note, causing a denial of service. No data is lost, as the original content of the affected notes is still present in the database.
This issue was fixed in version 1.9.9. As a workaround, disabling freeURL mode prevents the exploitation of this issue. The impact can be limited by restricting freeURL note creation to trusted, logged-in users by enabling `requireFreeURLAuthentication`/`CMD_REQUIRE_FREEURL_AUTHENTICATION`.
