Heap overflow

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. ...

Command injection

An exploitable command injection vulnerability exists in the DHCP daemon configuration of the CUJO Smart Firewall. When adding a new static DHCP address, its corresponding hostname is inserted into the dhcpd.conf file without prior sanitization, allowing for arbitrary execution of system commands...

Integer overflow

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...

Cross site request forgery (csrf)

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...

Design/Logic Flaw

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 vulnerabilit...

CVE-2018-3963

An exploitable command injection vulnerability exists in the DHCP daemon configuration of the CUJO Smart Firewall. When adding a new static DHCP address, its corresponding hostname is inserted into the dhcpd.conf file without prior sanitization, allowing for arbitrary execution of system commands...

CVE-2018-3963

The CVE-2018-3963 issue affects the CUJO Smart Firewall: the DHCP daemon’s static-hostname handling inserts the hostname into dhcpd.conf without sanitization, enabling arbitrary command execution as root when a static DHCP entry is configured. The vulnerability can be triggered by a DHCP request ...

CVE-2018-4030

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...

CVE-2018-4030

CVE-2018-4030 describes a vulnerability in the CUJO Smart Firewall (firmware 7003) where the safe-browsing HTTP/HTTPS host header is parsed incorrectly. The host value extracted from captured requests can be manipulated, enabling an attacker to bypass the firewall’s web-reputation checks and reac...

CVE-2018-4011

CUJO Smart Firewall mdnscap (firmware 7003) is affected by CVE-2018-4011: an integer underflow in SRV RDATA parsing during mDNS DNS RR processing leads to out-of-bounds heap access and a crash of the mdnscap process. The flaw arises when rdlength is small (e.g., 0x05) and the code subtracts 6 wit...

CVE-2018-3985

CVE-2018-3985 affects CUJO Smart Firewall, specifically the mdnscap mDNS parsing code. The TALOS advisory details an exploitable double-free vulnerability during mDNS packet parsing that frees memory twice when an invalid query name is encountered, enabling arbitrary code execution in the mdnscap...

CVE-2018-3985

An exploitable double free vulnerability exists in the mdnscap binary of the CUJO Smart Firewall. When parsing mDNS packets, a memory space is freed twice if an invalid query name is encountered, leading to arbitrary code execution in the context of the mdnscap process. An unauthenticated attacke...

CVE-2018-3969

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 vulnerabilit...

CVE-2018-3969

CVE-2018-3969 affects the CUJO Smart Firewall and describes a verified-boot bypass via embedding shell commands in /config/dhcpd.conf. Cisco Talos reports that an attacker who can write to /config/dhcpd.conf can cause the DHCP server to execute commands at boot, persisting across reboots and firm...

CVE-2018-4003

The CVE-2018-4003 issue affects CUJO Smart Firewall (firmware 7003) in the mdnscap mDNS parser. A heap-based buffer overflow occurs when parsing string lengths in mDNS resource records, allowing an unauthenticated remote attacker to trigger arbitrary code execution in the mdnscap process; exploit...
