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

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 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.

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.

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).

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

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

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

An Integer-based buffer overflow vulnerability in the SonicOS via IPSec allows a remote attacker in specific conditions to cause Denial of Service (DoS) and potentially execute arbitrary code by sending a specially crafted IKEv2 payload.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in the SonicOS SSLVPN portal allows a remote authenticated attacker as a firewall 'admin' user to store and execute arbitrary JavaScript code.

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

A post-authentication Format String vulnerability in SonicOS allows a remote attacker to crash a firewall.

A post-authentication NULL Pointer Dereference vulnerability in SonicOS allows a remote attacker to crash a firewall.

A post-authentication Out-of-bounds Read vulnerability in SonicOS allows a remote attacker to crash a firewall.

Multiple post-authentication stack-based buffer overflow vulnerabilities in the SonicOS management interface due to improper bounds checking in a API endpoint.

SonicOS post-authentication Improper Privilege Management vulnerability in the SonicOS SSL VPN Tunnel allows users to elevate their privileges inside the tunnel.

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.

A Null Pointer Dereference vulnerability in the SonicOS SSLVPN Virtual office interface allows a remote, unauthenticated attacker to crash the firewall, potentially leading to a Denial-of-Service (DoS) condition.

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

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.

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.

Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in the SonicOS SSLVPN authentication token generator that, in certain cases, can be predicted by an attacker potentially resulting in authentication bypass.

An Integer-based buffer overflow vulnerability in the SonicOS via IPSec allows a remote attacker in specific conditions to cause Denial of Service (DoS) and potentially execute arbitrary code by sending a specially crafted IKEv2 payload.

A vulnerability in SonicWall SonicOS and SonicOSv TLS CBC Cipher allow remote attackers to obtain sensitive plaintext data when CBC cipher suites are enabled. This vulnerability affected SonicOS Gen 5 version 5.9.1.10 and earlier, Gen 6 version 6.2.7.3, 6.5.1.3, 6.5.2.2, 6.5.3.1, 6.2.7.8, 6.4.0.0, 6.5.1.8, 6.0.5.3-86o and SonicOSv 6.5.0.2-8vRC363 (VMWARE), 6.5.0.2.8vRC367 (AZURE), SonicOSv 6.5.0.2.8vRC368 (AWS), SonicOSv 6.5.0.2.8vRC366 (HYPERV).
