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-2021-31401

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-2021-31228

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...

CVE-2021-36762

CVE-2021-36762 affects HCC Embedded InterNiche NicheStack and NicheLite up to version 4.3. The tfshnd():tftpsrv.c TFTP packet processing function may read beyond the protocol buffer when a filename isn’t properly NULL-terminated, enabling out-of-bounds reads and potential DoS. Impact is described...

CVE-2021-31400

CVE-2021-31400 affects HCC Embedded InterNiche/NicheStack TCP/IP stack (in tcp_pulloutofband() in tcp_in.c, 4.0.1) where out-of-band urgent data handling may call a panic, potentially causing an infinite loop and DoS.

CVE-2021-31227

CVE-2021-31227 affects HCC Embedded InterNiche/NicheStack. It is a heap-buffer-overflow in the HTTP POST parsing path (wbs_multidata) caused by an incorrect signed-integer comparison. Exploitation requires sending a malformed HTTP packet with a negative Content-Length, bypassing size checks and t...

CVE-2021-31226

CVE-2021-31226 affects HCC Embedded InterNiche/NicheStack (4.0.1) and is caused by a lack of input size validation in the HTTP POST parser, leading to a heap buffer overflow in wbs_post() via strcpy() when a crafted URI longer than 50 bytes is sent. Red Hat/RedHat CVE entries corroborate a heap o...

CVE-2021-36762: Undefined Security Weakness
