The vulnerability of the implementations of the ISN generators for TCP/IP NicheLite and InterNiche allows attackers to perform spoofing attacks.
The vulnerability of the ISN generator implementations for TCP/IP NicheLite and InterNiche is related to the use of insufficiently random values. Exploiting this vulnerability allows a remote attacker to perform spoofing attacks...
The vulnerability of DNS-client TCP/IP clients of NicheLite and InterNiche allows attackers to perform spoofing attacks.
The vulnerability of TCP/IP NicheLite and InterNiche clients stems from the use of insufficiently random values. Exploiting this vulnerability allows a malicious actor to perform spoofing attacks remotely...
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 '\0' terminated; therefore, a subsequent call to strlen for the filename might read out of bounds of the protocol packet...
CVE-2021-27565
The web server in InterNiche NicheStack through 4.0.1 allows remote attackers to cause a denial of service infinite loop and networking outage via an unexpected valid HTTP request such as OPTIONS. This occurs because the HTTP request handler enters a miscoded wbsloop debugger hook...
CVE-2021-31401
An issue was discovered in tcprcv 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...

CVE-2021-31401
CVE-2021-31401 affects HCC Embedded’s InterNiche/NicheStack TCP/IP stack (InterNiche 4.0.1). The issue is an improper input validation in TCP/IP processing: the TCP/IP stack does not validate the IP total length, allowing a crafted IP packet to trigger an integer overflow in tcp_rcv() (nptcp.c). ...
CVE-2021-31227
An issue was discovered in HCC embedded InterNiche 4.0.1. A potential heap buffer overflow exists in the code that parses the HTTP POST request, due to an incorrect signed integer comparison. This vulnerability requires the attacker to send a malformed HTTP packet with a negative Content-Length,...
CVE-2021-31226
An issue was discovered in HCC embedded InterNiche 4.0.1. A potential heap buffer overflow exists in the code that parses the HTTP POST request, due to lack of size validation. This vulnerability requires the attacker to send a crafted HTTP POST request with a URI longer than 50 bytes. This leads...

CVE-2021-31228
An issue was discovered in HCC embedded InterNiche 4.0.1. This vulnerability allows the attacker to predict a DNS query's source port in order to send forged DNS response packets that will be accepted as valid answers to the DNS client's requests without sniffing the specific request. Data is...
CVE-2021-31400
An issue was discovered in tcppulloutofband in tcpin.c in HCC embedded InterNiche 4.0.1. The TCP out-of-band urgent-data processing function invokes a panic function if the pointer to the end of the out-of-band data points outside of the TCP segment's data. If the panic function hadn't a trap...
