### Description ### [GHSA-5mcr-gq6c-3hq2](https://github.com/netty/netty/security/advisories/GHSA-5mcr-gq6c-3hq2) (CVE-2021-21290) contains an insufficient fix for the vulnerability identified. ### Impact ### When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users. ### Vulnerability Details ### To fix the vulnerability the code was changed to the following: ```java @SuppressJava6Requirement(reason = "Guarded by version check") public static File createTempFile(String prefix, String suffix, File directory) throws IOException { if (javaVersion() >= 7) { if (directory == null) { ...

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors might be helpful in your situation: This vulnerability is not exploitable in NFSV4.1. Prior to updating your version of Windows that protects against this vulnerability, you can mitigate an attack by disabling NFSV2 and NFSV3. This may adversely affect your ecosystem and should only be used as a temporary mitigation. The following PowerShell command will disable those versions: PS C:\Set-NfsServerConfiguration -EnableNFSV2 $false -EnableNFSV3 $false After this, you will need to restart NFS server or reboot the machine. To restart NFS server, start a **cmd** window with **Run as Administrator**, enter the following commands: * **nfsadmin server stop** * **nfsadmin server start** To confirm that NFSv2 and NFSv3 have been turned off, run the following command in a Powershe...

What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** This vulnerability's attack is limited at the protocol level to a logically adjacent topology. This means it cannot simply be done across the internet, but instead needs something specific tied to the target. Good examples would include the same shared physical network (such as Bluetooth or IEEE 802.11), logical network (local IP subnet), or from within a secure or otherwise limited administrative domain (MPLS, secure VPN to an administrative network zone). This is common to many attacks that require man-in-the-middle type setups or that rely on initially gaining a foothold in another environment.

1Password for Mac 7.2.4 through 7.9.x before 7.9.3 is vulnerable to a process validation bypass. Malicious software running on the same computer can exfiltrate secrets from 1Password provided that 1Password is running and is unlocked. Affected secrets include vault items and derived values used for signing in to 1Password.

Craft CMS through 3.7.36 allows a remote unauthenticated attacker, who knows at least one valid username, to reset the account's password and take over the account by providing a crafted HTTP header to the application while using the password reset functionality. Specifically, the attacker must send X-Forwarded-Host to the /index.php?p=admin/actions/users/send-password-reset-email URI. NOTE: the vendor's position is that a customer can already work around this by adjusting the configuration (i.e., by not using the default configuration).
