A permissive cross-domain policy vulnerability has been identified in the SonicOS management interface, which in specific conditions could potentially enable a remote unauthenticated attacker to perform unauthorized operations.

A session validation vulnerability has been identified in the SonicOS management interface, which in specific conditions could potentially enable a remote unauthenticated attacker to perform unauthorized operations.

A pre-authentication heap-based buffer overflow vulnerability has been identified in the SonicOS TACACS+ authentication client, which in specific conditions could potentially enable a remote unauthenticated attacker to cause an application level denial of service.

A weak password hashing vulnerability has been identified on SonicOS virtual appliances, which in specific conditions could potentially enable an attacker with existing local access to disclose a platform credential. The credential provides access to a limited subset of platform settings.

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signaturealgorithms extension (where it was present in the initial ClientHello), but includes a signaturealgorithmscert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

OpenSSL could allow a remote attacker to bypass security restrictions, caused by a a missing check in the validation logic of X.509 certificate chains by the X509VFLAGX509STRICT flag. By using any valid certificate or certificate chain to sign a specially crafted certificate, an attacker could bypass the check that non-CA certificates must not be able to issue other certificates and override the default purpose.

A fundamental design flaw within the RADIUS protocol has been proven to be exploitable, compromising the integrity in the RADIUS Access-Request process. The attack allows a malicious user to modify packets in a way that would be indistinguishable to a RADIUS client or server. To be successful, the attacker must have the ability to inject themselves between the client and server.

A improper neutralization of HTTP Headers for Scripting Syntax vulnerability in SonicOS could allow a remote attacker to manipulate the Host header and redirect firewall management users to arbitrary web domains.

An improper access control vulnerability has been identified in the SonicWall SonicOS management access, potentially leading to unauthorized resource access and in specific conditions, causing the firewall to crash. This issue affects SonicWall Firewall Gen 5 and Gen 6 devices, as well as Gen 7 devices running SonicOS 7.0.1-5035 and older versions.

An Improper Authentication vulnerability in the SSLVPN authentication mechanism allows a remote attacker to bypass authentication.

An improper authentication vulnerability has been identified in SonicWall SonicOS SSL-VPN feature, which in specific conditions could allow a remote attacker to bypass authentication.

This issue affects only firmware version SonicOS 7.1.1-7040.

A buffer overflow vulnerability in SonicOS allows a remote attacker to cause Denial of Service (DoS) and potentially execute arbitrary code by sending a malicious request to the firewall. This vulnerability affected SonicOS Gen 6 version 6.5.4.7, 6.5.1.12, 6.0.5.3, SonicOSv 6.5.4.v and Gen 7 version 7.0.0.0.

A Stack-based buffer overflow vulnerability in the SonicOS SSLVPN service allows a remote unauthenticated attacker to cause Denial of Service (DoS), which could cause an impacted firewall to crash.

Just a heads up to anyone with SonicWall firewalls. Apparently SonicOS 7.0.1-5169 is subject to CVE-2025-27152 via Axios. Don't see anything posted from SonicWall around this, but apparently they are tracking via PSIRT-1935. Should hopefully be covered in the next firmware update.
