Heap overflow

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,...

Information disclosure

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-2020-35683

An issue was discovered in HCC Nichestack 3.0. The code that parses ICMP packets relies on an unchecked value of the IP payload size extracted from the IP header to compute the ICMP checksum. When the IP payload size is set to be smaller than the size of the IP header, the ICMP checksum computati...

CVE-2020-35683

CVE-2020-35683 affects HCC Embedded/InterNiche Nichestack/NicheLite prior to version 4.3. The root cause is an unchecked IP payload size used to compute the ICMP checksum, which can cause an out-of-bounds read and lead to Denial-of-Service. Red Hat notes the in_ipv4 module (v1.5) as impacted; CIS...

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-2021-36762

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-2021-31400

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. Public sources (NVD, Red Hat CVE page, CERT/ICS, ENISA ENISA, and ICSA Update B...

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-2021-31228

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-2021-31228

CVE-2021-31228 is a vulnerability in HCC Embedded’s InterNiche/NicheStack TCP/IP stack. The issue allows an attacker to predict the DNS query source port, enabling forged DNS responses to be accepted as valid by a DNS client (without needing to sniff the specific query). The Common details indica...

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-2020-25767

An issue was discovered in HCC Embedded NicheStack IPv4 4.1. The dnccopyin routine for parsing DNS domain names does not check whether a domain name compression pointer is pointing within the bounds of the packet e.g., forward compression pointer jumps are allowed, which leads to an Out-of-bounds...

CVE-2020-25767

CVE-2020-25767 affects HCC Embedded InterNiche/NicheStack (IPv4) prior to 4.3. The root cause is in the dnc_copy_in DNS domain name parser, which fails to validate that compression pointers stay within packet bounds, enabling an out-of-bounds read and potential DoS via crafted DNS data. Affected ...
