CVE-2021-36762

An issue was discovered in HCC Embedded InterNiche NicheStack through 4.3. The tfshnd():tftpsrv.c TFTP packet processing function doesn’t ensure that a filename is adequately ‘{$content}’ terminated; therefore, a subsequent call to strlen for the filename might read out of bounds of the protocol packet buffer (if no ‘{$content}’ byte exists within a reasonable range).

CVE-2021-39273

In XeroSecurity Sn1per 9.0 (free version), insecure permissions (0777) are set upon application execution, allowing an unprivileged user to modify the application, modules, and configuration files. This leads to arbitrary code execution with root privileges.

CVE-2021-39274

In XeroSecurity Sn1per 9.0 (free version), insecure directory permissions (0777) are set during installation, allowing an unprivileged user to modify the main application and the application configuration file. This results in arbitrary code execution with root privileges.

CVE-2020-35684

An issue was discovered in HCC Nichestack 3.0. The code that parses TCP packets relies on an unchecked value of the IP payload size (extracted from the IP header) to compute the length of the TCP payload within the TCP checksum computation function. When the IP payload size is set to be smaller than the size of the IP header, the TCP checksum computation function may read out of bounds (a low-impact write-out-of-bounds is also possible).

CVE-2021-31401

An issue was discovered in tcp_rcv() in nptcp.c in HCC embedded InterNiche 4.0.1. The TCP header processing code doesn’t sanitize the value of the IP total length field (header length + data length). With a crafted IP packet, an integer overflow occurs whenever the value of the IP data length is calculated by subtracting the length of the header from the total length of the IP packet.
