An issue was discovered in Stormshield Network Security (SNS) 4.3.x before 4.3.35. If multicast streams are enabled on different interfaces, it may be possible to interrupt multicast traffic on some of these interfaces. That could result in a denial of the multicast routing service on the firewall.
An issue was discovered in Stormshield Network Security (SNS) SNS 4.3.13 through 4.3.22 before 4.3.23, SNS 4.6.0 through 4.6.9 before 4.6.10, and SNS 4.7.0 through 4.7.1 before 4.7.2. An attacker can overflow the cookie threshold, making an IPsec connection impossible.
An issue was discovered in Stormshield Network Security (SNS) 3.7.0 through 3.7.38 before 3.7.39, 3.10.0 through 3.11.26 before 3.11.27, 4.0 through 4.3.21 before 4.3.22, and 4.4.0 through 4.6.8 before 4.6.9. An administrator with write access to the SNS firewall can configure a login disclaimer with malicious JavaScript elements that can result in data theft.
ASQ in Stormshield Network Security (SNS) 4.3.15 before 4.3.16 and 4.6.x before 4.6.3 allows a crash when analysing a crafted SIP packet.
Flooding SNS firewall versions 3.7.0 to 3.7.29, 3.11.0 to 3.11.17, 4.2.0 to 4.2.10, and 4.3.0 to 4.3.6 with specific forged traffic, can lead to SNS DoS.
An issue was discovered in Stormshield Network Security (SNS) 4.3.x before 4.3.8. The event logging of the ASQ sofbus lacbus plugin triggers the dereferencing of a NULL pointer, leading to a crash of SNS. An attacker could exploit this vulnerability via forged sofbus lacbus traffic to cause a firmware crash.
In Stormshield Network Security (SNS) before 3.7.25, 3.8.x through 3.11.x before 3.11.13, 4.x before 4.2.10, and 4.3.x before 4.3.5, a flood of connections to the SSLVPN service might lead to saturation of the loopback interface. This could result in the blocking of almost all network traffic, making the firewall unreachable. An attacker could exploit this via forged and properly timed traffic to cause a denial of service.
In ASQ in Stormshield Network Security (SNS) 1.0.0 through 2.7.8, 2.8.0 through 2.16.0, 3.0.0 through 3.7.20, 3.8.0 through 3.11.8, and 4.0.1 through 4.2.2, mishandling of memory management can lead to remote code execution.
Stormshield Network Security (SNS) before 4.2.2 allows a read-only administrator to gain privileges via CLI commands.
In Stormshield SSO Agent 2.x before 2.1.1 and 3.x before 3.0.2, the cleartext user password and PSK are contained in the log file of the .exe installer.
An issue was discovered in Stormshield Network Security (SNS) 4.2.2 through 4.2.7 (fixed in 4.2.8). Under a specific update-migration scenario, the first SSH password change does not properly clear the old password.
Stormshield SNS with versions before 3.7.18, 3.11.6 and 4.1.6 has a memory-management defect in the SNMP plugin that can lead to excessive consumption of memory and CPU resources, and possibly a denial of service.
The ClamAV Engine (version 0.103.1 and below) component embedded in Storsmshield Network Security (SNS) is subject to DoS in case of parsing of malformed png files. This affect Netasq versions 9.1.0 to 9.1.11 and SNS versions 1.0.0 to 4.2.0. This issue is fixed in SNS 3.7.19, 3.11.7 and 4.2.1.
