### Summary In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error. ### Details A flaw in the authentication check process allows an attacker to specify any arbitrary username that does not exist on the system, along with a salted hash of an empty password. Under these conditions, Navidrome treats the request as authenticated, granting access to various Subsonic endpoints without requiring valid credentials. ### Proof of Concept (PoC) 1. Generate a random salt: ```javascript // e.g., salt = "x1vbudn1m6d" Math.random().toString(36).substring(2, 15) ``` 2. Calculate the MD5 hash of an empty password plus the salt: ```shell # Using the example salt above echo -n "x1vbudn1m6d" | md5sum 81f0c0fb5d202ab0d012e6eaeb722d79 - ``` 3. Send a re...
Ultra-wideband radio has been heralded as the solution for “relay attacks” that are used to steal cars in seconds. But researchers found Teslas equipped with it are as vulnerable as ever.
The MStore API plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.9.1. This is due to insufficient verification on the user being supplied during the cart sync from mobile REST API request through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the user id.
The legislation would insert the government into online platforms' age-verification efforts—a move that makes some US lawmakers queasy.
An issue was discovered in the Linux kernel through 5.16-rc6. ef100_update_stats in drivers/net/ethernet/sfc/ef100_nic.c lacks check of the return value of kmalloc().
### Impact Mutagen projects offer shell-based execution functionality. On Windows, the shell is resolved using the standard `%ComSpec%` mechanism, with a fallback to a `%PATH%`-based search for `cmd.exe`. While this is the standard practice on Windows systems, it presents somewhat risky behavior. Firstly, `%ComSpec%` could, in theory, be set maliciously. Unfortunately, there's not much that can be done to prevent this attack surface, because `%ComSpec%` is the official mechanism for shell specification on Windows. We can, however, validate that it points to an absolute path, which one would expect for a properly set value. Secondly, a fallback to a relative `cmd.exe` path, resolved via `%PATH%`, could be risky. The risk is largely mitigated by changes in Go 1.19 and later, but prior to that a malicious `cmd.exe` could been resolved in the current working directory. To mitigate this issue, Mutagen now uses the `%SystemRoot%` environment variable (also validated to be an absolut...
Authorities have sanctioned 11 alleged members of the cybercriminal groups, while the US Justice Department unsealed three federal indictments against nine people accused of being members.
