Where to report

The one public program Zeek runs.

Amounts are the top reward per severity in the currency each program pays. First response is the platform's measured average when it publishes one, else what the policy promises.

What is in scope

7 targets. 6 excluded.

  • https://zeek.org

    Web

  • File analysis and extraction under file_analysis in full, including the MIME and hash pipelines that reassemble transferred content

    Products and areas

  • The Broker communication library and the whole cluster control plane between manager, proxies, loggers and workers, where sensor nodes trust each other

    Products and areas

  • The entire analyser corpus under src/analyzer/protocol, plus the SPICY-generated analysers, all of which parse untrusted wire data straight off the tap

    Products and areas

  • The input framework and every log writer, where attacker-influenced field values reach an output serialiser and then a downstream SIEM

    Products and areas

  • The Zeek scripting language end to end: the interpreter, its type system, and the script-driven memory management behind it

    Products and areas

  • Zeek takes security reports at [email protected] under a documented security release process with a bounded embargo. The covered object is the Zeek tree in full, and no boundary narrower than that is drawn

    Products and areas

No target matches. Try part of a host name, such as the company name.

Out of scope 6

Don't test these. A program can exclude a host another program covers; the program you report to decides.

  • Anything not merged upstream, and anything reverted within the first month after it lands

  • Corelight's commercial sensor software, which embeds Zeek but is a separate product

  • Detection-logic gaps in community scripts rather than defects in the engine itself

  • One-liner non-exploitable crash fixes, which the reward rules place below the bar

  • Patches younger than one month or older than twelve, which the reward age window excludes at both ends

  • Zeek package-manager packages authored by third parties, which are not this tree

  • Zeek before 8.0.9 contains an uncontrolled memory consumption vulnerability in the FTP analyzer that allows unauthenticated remote attackers to cause process termination by sending a crafted FTP control session negotiating AUTH GSSAPI followed by a large ADAT control line. Attackers can exploit the NVT_Analyzer component's lack of a maximum line length check, causing it to continuously double its

  • Zeek before 8.0.9 contains a null pointer dereference vulnerability in its Kerberos protocol analyzer that allows unauthenticated remote attackers to crash the sensor by sending a crafted KRB_ERROR message with error-code 25 (KDC_ERR_PREAUTH_REQUIRED) containing a PA-DATA element with padata-type 2, 3, 11, or 19. Attackers can exploit a parser and analyzer state mismatch where proc_padata() derefe

  • An issue was discovered in zeek version 4.1.0. There is a HTTP request splitting vulnerability that will invalidate any ZEEK HTTP based security analysis. NOTE: the vendor's position is that the observed behavior is intended

  • In Zeek Network Security Monitor (formerly known as Bro) before 2.6.2, a NULL pointer dereference in the Kerberos (aka KRB) protocol parser leads to DoS because a case-type index is mishandled.
