GHSA-6W3V-8X64-R348

Vulnerability from github – Published: 2024-04-12 15:37 – Updated: 2025-05-19 12:30
VLAI
Details

An Improper Handling of Exceptional Conditions vulnerability in the Class of Service daemon (cosd) of Juniper Networks Junos OS on MX Series allows an authenticated, network-based attacker with low privileges to cause a limited Denial of Service (DoS).

In a scaled subscriber scenario when specific low privileged commands, received over NETCONF, SSH or telnet, are handled by cosd on behalf of mgd, the respective child management daemon (mgd) processes will get stuck. In case of (Netconf over) SSH this leads to stuck SSH sessions, so that when the connection-limit for SSH is reached new sessions can't be established anymore. A similar behavior will be seen for telnet etc.

Stuck mgd processes can be monitored by executing the following command:

user@host> show system processes extensive | match mgd | match sbwait

This issue affects Juniper Networks Junos OS on MX Series: All versions earlier than 20.4R3-S9; 21.2 versions earlier than 21.2R3-S7; 21.3 versions earlier than 21.3R3-S5; 21.4 versions earlier than 21.4R3-S5; 22.1 versions earlier than 22.1R3-S4; 22.2 versions earlier than 22.2R3-S3; 22.3 versions earlier than 22.3R3-S2; 22.4 versions earlier than 22.4R3; 23.2 versions earlier than 23.2R1-S2, 23.2R2.

Details

A flaw was found in dbus-broker. When the process file-descriptor limit is reached, EMFILE/ENFILE errors during peer setup (notably SO_PEERPIDFD) are handled as fatal failures, causing the broker to exit. A local attacker who can open many connections to the user session bus can trigger this and deny service to the desktop session. Flatpak applications can reach the host session bus through the dbus proxy.

Summary
Directus vulnerable to unhandled exception on illegal filename_disk value
Details

The Directus process can be aborted by having an authorized user update the filename_disk value to a folder and accessing that file through the /assets endpoint.

The vulnerability is patched and released in v9.15.0.

You can prevent this problem by making sure no (untrusted) non-admin users have permissions to update the filename_disk field on directus_files.
