"text": "Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR.\n\nNet::DNS::RR::OPT::EXTENDED_ERROR::_decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option (RFC 8914) by tokenising the raw bytes and passing the result to Perl's eval. There is some escaping done for $ and @, but not for backticks. This can be exploited for command execution if $pkt->edns->option('EXTENDED-ERROR') is called in array context, for example with a payload of {0:`\"<command>\"`} in EXTRA-TEXT.",

{
"category": "general",
"text": "Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR.\n\nNet::DNS::RR::OPT::EXTENDED_ERROR::_decompose parses the EXTRA-TEXT field of an EDNS EXTENDED-ERROR option (RFC 8914) by tokenising the raw bytes and passing the result to Perl's eval. There is some escaping done for $ and @, but not for backticks. This can be exploited for command execution if $pkt->edns->option('EXTENDED-ERROR') is called in array context, for example with a payload of {0:`\"<command>\"`} in EXTRA-TEXT.",
