AV:N and PR:N/UI:N since a network DNS response triggers it without auth, but AC:H because the app must call the EXTENDED-ERROR option in array context and attacker must control the response; full CIA loss from code execution.

Net::DNS versions through 1.55 for Perl allow remote execution injection via EDNS EXTENDED ERROR.
Net::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.
AnalysisAI
Eval-based command injection in the Net::DNS module for Perl (versions through 1.55) lets a malicious or man-in-the-middle DNS server run arbitrary shell commands on a client that parses an EDNS EXTENDED-ERROR option. The EXTRA-TEXT field is tokenised and passed to Perl's eval with escaping for $ and @ but not backticks, so a crafted response reaching option('EXTENDED-ERROR') in array context executes attacker-supplied commands. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that (1) the victim runs Net::DNS ≤1.55 for Perl and processes a DNS response that includes an EDNS0 EXTENDED-ERROR (RFC 8914) option, and (2) the application code specifically calls $pkt->edns->option('EXTENDED-ERROR') in array (list) context - the exact API usage that routes EXTRA-TEXT into eval. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals conflict in an informative way. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who controls a DNS server (or can man-in-the-middle DNS responses to a target) returns a response containing an EDNS EXTENDED-ERROR option whose EXTRA-TEXT holds a payload like {0:`"id > /tmp/pwned"`}. When the victim Perl application parses that response and reads the extended-error option in array context, Net::DNS passes the backtick-laden string to eval and the embedded command runs with the application's privileges. … |
| Remediation | Upstream fix available (Net::DNS 1.55_01 developer release and 1.56 release candidate); a final tagged 1.56 stable release should be confirmed on CPAN before deployment, so treat this as 'released patched version not yet independently confirmed as GA' and upgrade to 1.56 as soon as it is published, or apply the 1.55_01 developer build in the interim per the changelog at https://metacpan.org/release/NLNETLABS/Net-DNS-1.55_01/changes. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all production systems using Net::DNS ≤1.55; alert application owners to the critical risk posed by any untrusted DNS traffic. …
