Access Control Bypass in SonicOS Management Functions

A vulnerability in the access control mechanism of SonicOS may allow certain management interface functions to be accessible under specific conditions.

Stack-based buffer overflow vulnerability in the SonicOS HTTP server allows an authenticated remote attacker to cause Denial of Service (DoS) via sscanf function.

SonicOS SSLVPN improper restriction of excessive MFA attempts vulnerability allows an authenticated attacker to use excessive MFA codes.

Heap-based buffer overflow vulnerability in the SonicOS SSL-VPN allows an authenticated remote attacker to cause Denial of Service (DoS) via memcpy function.

A Stack-based buffer overflow in the SonicOS HTTP Content-Length response header allows a remote authenticated attacker to cause Denial of Service (DoS) and potentially results in code execution in the firewall. This vulnerability affected SonicOS Gen 5, Gen 6 and Gen 7 firmware versions.

A Stack-based buffer overflow in the SonicOS SessionID HTTP response header allows a remote authenticated attacker to cause Denial of Service (DoS) and potentially results in code execution in the firewall. This vulnerability affected SonicOS Gen 5, Gen 6 and Gen 7 firmware versions.

A Host Header Redirection vulnerability in SonicOS potentially allows a remote attacker to redirect firewall management users to arbitrary web domains.

A Stack-based buffer overflow vulnerability in the SonicOS via HTTP request allows a remote unauthenticated attacker to cause Denial of Service (DoS) or potentially results in code execution in the firewall.

Post-Authentication Path Traversal in SonicOS Enabling Restricted Service Access

A post-authentication Path Traversal vulnerability in SonicOS allows an attacker to interact with usually restricted services.

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.

Post‑Authentication Buffer Overflow in SonicOS Causes Firewall Crash

A post-authentication Stack-based Buffer Overflow vulnerabilities in SonicOS allows a remote attacker to crash a firewall.

A buffer overflow vulnerability in SonicOS allows a remote attacker to cause a Denial of Service (DoS) by sending a specially crafted request. This vulnerability affects SonicOS Gen5, Gen6, Gen7 platforms, and SonicOSv virtual firewalls.

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

Permissive Cross‑Domain Policy in SonicOS Management Interface Allows Remote Unauthenticated Operations

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.

SonicOS TACACS+ Client Buffer Overflow Allows Unauthenticated Denial of Service

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.

Weak Password Hashing Vulnerability in SonicOS Virtual Appliances Allowing Local Credential Disclosure

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.

Stack‑Based Buffer Overflow in SonicOS TACACS+ Client Causing Unauthenticated Denial of Service

A pre-authentication stack-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.

Unauthenticated Remote Heap Overflow in SonicOS SSL‑VPN Service

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

SonicOS Management Interface Session Validation Vulnerability Allowing 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.

NULL pointer deref in signature_algorithms processing

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 signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert 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).
