CVE-2021-44228

Certain KGUARD DVR devices running vulnerable firmware expose a system command execution service on all network interfaces without requiring authentication. A remote unauthenticated attacker can execute arbitrary system commands, potentially leading to complete compromise. Exploited by Mirai_ptea and Mirai_aurora botnets for malware propagation and DDoS.

An unauthenticated remote code execution vulnerability exists in the Policy Manager console of Akana API Platform. A path normalization discrepancy allows authentication bypass and access to an endpoint that executes attacker-supplied script code without sandboxing, leading to arbitrary code execution.

A Code Injection vulnerability in adk web in Google Cloud Agent Development Kit (ADK) for Python versions 2.0.0 through 2.6.0 on Python (OSS), Cloud Run, and GKE environments where pytest is installed allows an unauthenticated remote attacker to execute arbitrary code using a crafted test session replay.

Use of less trusted source vulnerability in PayTR Virtual Pos iFrame API (v9x) WHMCS Module allows Exploitation of Trusted Identifiers. This issue affects versions from v9.0.0 before v9.0.3.

Use-after-free vulnerability in DualDAR prior to SMR Sep-2026 Release 1 allows local privileged attackers to execute arbitrary code with root privilege.

Heap-based buffer overflow in JPEG decoder of libimagecodec.quram.so prior to SMR Sep-2026 Release 1 allows remote attackers to execute arbitrary code.

Heap-based buffer overflow in DNG decoder of libimagecodec.quram.so prior to SMR Sep-2026 Release 1 allows remote attackers to execute arbitrary code.

In cjose versions 0.6.1 through 0.6.2.5, when encrypting a JWE using AES-CBC-HMAC content-encryption algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) with any key-management algorithm that generates a fresh content-encryption key (CEK), the CEK is all zero bytes instead of being randomly generated. The resulting JWE is encrypted and authenticated under a fixed, publicly known key, allowing anyone who obtains the JWE to recover plaintext and forge or modify content. Fixed in 0.6.2.6 by generating CEK from RAND_bytes.

OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and write user-controlled data to any file.

The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host, could insert script content that executes in an administrator's browser.
