A vulnerability has been identified in the SSH daemon of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to gain administrative access to vulnerable AFC hosts. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system leading to complete system compromise.

In openNDS before 11.0.0, the client_params.sh script, invoked by the openNDS daemon to serve the authenticated client status page, is vulnerable to OS command injection through crafted HTTP GET query parameter keys. An authenticated captive portal user can inject arbitrary shell commands by embedding semicolons in a URL query parameter name.

NebulaGraph exposes its runtime configuration over an unauthenticated HTTP service. Each daemon starts the web service defined in src/webservice/WebService.cpp, whose bind address defaults to all interfaces, and registers routes for reading and writing gflags alongside status and statistics. Neither the service nor its router carries any authentication, token check or address restriction. The read…

The OpenRGB network protocol allows to write attacker controlled strings into arbitrary file system paths (extension of CVE-2026-59682). This allows either a full system compromise from local or remote (if the daemon is running as root) or a full account takeover (if the daemon is running in user context).

Incus is a system container and virtual machine manager. Prior to version 7.3.0, an unprivileged, project-confined Incus user (a non-admin TLS/RBAC identity with `can_create_images` and `can_create_instances`) can execute arbitrary code as root on the host. A crafted image ships `backup.yaml` as a symlink to a host file. When the root daemon writes the instance's backup file, it follows the symlin…

A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denia…

Netatalk is a Free and Open Source file server suite for Unix-like operating systems. In versions 3.1.19 through 4.4.2, a stack-based buffer overflow exists in the deletedir() function of Netatalk's afpd daemon due to an integer underflow in the calculation of the remaining buffer size used for path construction. deletedir() is a utility function called when a file operation crosses a device bound…

OpenWrt LuCI contains an overly permissive ACL definition in luci-mod-system-mounts that grants write access to /etc/crontabs/root to users intended only for mount configuration. Authenticated users with only the mount-configuration ACL group can append arbitrary cron entries via ubus file.write, which the default busybox crond daemon executes as root within one minute.

rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based deny rule fails, the daemon skips the rule rather than defaulting to a deny decision, enabling attackers who can trigger DNS failures to bypass…
