CVE-2018-4031 (GCVE-0-2018-4031)
Vulnerability from nvd – Published: 2019-10-31 20:29 – Updated: 2024-08-05 05:04
VLAI
Summary
An exploitable vulnerability exists in the safe browsing function of the CUJO Smart Firewall, version 7003. The flaw lies in the way the safe browsing function parses HTTP requests. The server hostname is extracted from captured HTTP/HTTPS requests and inserted as part of a Lua statement without prior sanitization, which results in arbitrary Lua script execution in the kernel. An attacker could send an HTTP request to exploit this vulnerability.
Severity
9 (Critical)
CWE
- Improper control of generation of code

CVE-2018-4011 (GCVE-0-2018-4011)
Vulnerability from nvd – Published: 2019-03-21 15:42 – Updated: 2024-08-05 04:57
VLAI
Summary
An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the "RDLENGTH" value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.

CVE-2018-3969 (GCVE-0-2018-3969)
Vulnerability from nvd – Published: 2019-03-21 15:26 – Updated: 2024-08-05 04:57
VLAI
Summary
An exploitable vulnerability exists in the verified boot protection of the CUJO Smart Firewall. It is possible to add arbitrary shell commands into the dhcpd.conf file, that persist across reboots and firmware updates, and thus allow for executing unverified commands. To trigger this vulnerability, a local attacker needs to be able to write into /config/dhcpd.conf.
Severity
8.2 (High)
CWE
- permissions, privileges, and access controls

CVE-2018-4031 (GCVE-0-2018-4031)
Vulnerability from cvelistv5 – Published: 2019-10-31 20:29 – Updated: 2024-08-05 05:04
VLAI
Summary
An exploitable vulnerability exists in the safe browsing function of the CUJO Smart Firewall, version 7003. The flaw lies in the way the safe browsing function parses HTTP requests. The server hostname is extracted from captured HTTP/HTTPS requests and inserted as part of a Lua statement without prior sanitization, which results in arbitrary Lua script execution in the kernel. An attacker could send an HTTP request to exploit this vulnerability.

CVE-2018-4030 (GCVE-0-2018-4030)
Vulnerability from cvelistv5 – Published: 2019-03-21 15:46 – Updated: 2024-08-05 05:04
VLAI
Summary
An exploitable vulnerability exists the safe browsing function of the CUJO Smart Firewall, version 7003. The bug lies in the way the safe browsing function parses HTTP requests. The "Host" header is incorrectly extracted from captured HTTP requests, which would allow an attacker to visit any malicious websites and bypass the firewall. An attacker could send an HTTP request to exploit this vulnerability.
Severity
5.3 (Medium)
CWE
- 'HTTP Request Smuggling

Summary
An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the "RDLENGTH" value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.

CVE-2018-3969 (GCVE-0-2018-3969)
Vulnerability from cvelistv5 – Published: 2019-03-21 15:26 – Updated: 2024-08-05 04:57

Summary
An exploitable vulnerability exists in the verified boot protection of the CUJO Smart Firewall. It is possible to add arbitrary shell commands into the dhcpd.conf file, that persist across reboots and firmware updates, and thus allow for executing unverified commands. To trigger this vulnerability, a local attacker needs to be able to write into /config/dhcpd.conf.

Summary
An exploitable heap overflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. The string lengths are handled incorrectly when parsing character strings in mDNS resource records, leading to arbitrary code execution in the context of the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.
