CVE-2026-28456

A vulnerability was found in Ruijie RG-EW3000GX EW_3.0(1)B11P380 within the user_list_note module in the file /etc/rg_config/admin. Manipulation of the Name argument leads to OS command injection. The attack can be performed remotely, and the exploit has been publicly disclosed.

A vulnerability in the internal configuration of the Apache JServ Protocol (AJP) connector for Cisco Secure FMC Software could allow an unauthenticated, remote attacker to impersonate a peer device. The issue is due to incorrect initialization of encryption parameters for the AJP connector at boot time. A successful exploit could allow the attacker to execute commands as root and gain full control over the FMC REST APIs, but only if the sftunnel connection between FMC and FTD is down.

Cisco conducted an internal security review that resulted in a software hardening release addressing multiple internally discovered vulnerabilities in Cisco Secure Adaptive Security Appliance Software, Cisco Secure Firewall Threat Defense Software, and Cisco Secure Firewall Management Center Software. The vulnerabilities tracked by CVE-2026-20331 relate to failure of protection mechanisms (CWE-693).

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system. The attacker must have at least low-privileged administrative credentials. The issue is due to insecure deserialization of a user-supplied Java byte stream; successful exploitation could allow code execution and privilege escalation to root, and in single-node deployments could cause the ISE node to become unavailable (DoS).

A vulnerability in the REST API of Cisco ISE and ISE-PIC could allow an authenticated, remote attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. The attacker must have valid administrative credentials. The issue is due to improper validation of user-supplied input; successful exploitation could allow arbitrary code execution, and in single-node deployments could cause the ISE node to become unavailable (DoS).

A vulnerability in the diagnostic tools of Cisco ISE and ISE-PIC could allow an authenticated, remote attacker to perform command injection attacks on the underlying operating system and elevate privileges to root. The attacker must have valid administrative credentials. The issue is due to improper validation of user-supplied input; successful exploitation could allow arbitrary code execution, and in single-node deployments could cause the ISE node to become unavailable (DoS).

Cisco conducted an internal security review that resulted in a software hardening release addressing multiple internally discovered vulnerabilities in Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC). The vulnerabilities tracked by CVE-2026-20234 relate to insufficiently protected credentials (CWE-522).

A vulnerability has been found in Ruijie RG-EW3000GX EW_3.0(1)B11P380 within the cc_set function of the file unifyframe-sgi.elf in the configChange component. Manipulation of the data.url argument leads to OS command injection. The attack may be performed remotely, and the exploit has been publicly disclosed.

Dell ObjectScale, versions prior to 4.4.0.0, contains a Deserialization of Untrusted Data vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to remote code execution.

LMDeploy implements an RPC server (AsyncRPCServer in zmq_rpc.py) whose call_and_response() function deserializes received messages using pickles.loads() without any sanitization. This allows remote code execution through the RPC server. The vulnerability exists from version 0.9.1 up to 0.10.2, where it is patched.
