suricata: 1 CWE-312 defect (suricata-0001); MOADs 0001/0002/0003/0005 CLEAN

MOAD-0004 CWE-312: EveHttpLogJSONHeaders() in output-json-http.c logs HTTP
credential headers (Authorization, Proxy-Authorization, Cookie, Set-Cookie)
verbatim when dump-all-headers or custom field logging is enabled. Patch adds
a credential denylist that emits "[REDACTED]" instead of the raw value.
Default suricata.yaml.in shows Authorization as a custom field example with
no warning. Unit test 5/5 PASS.

MOADs 0001/0002/0003/0005 CLEAN: bitarray+hash+radix+RB-tree hot paths,
per-tenant DetectEngineCtx, thread-scoped thread_local, HRLOCK-guarded THash.

+/**
+ * suricata-0001 — CWE-312: HTTP credential headers logged verbatim
+ *
+ * File: src/output-json-http.c, function: EveHttpLogJSONHeaders()
+ *
+ * Defect: When Suricata's eve-log HTTP module is configured with
+ * dump-all-headers (both/request/response) or a custom field list
+ * that includes "authorization", "proxy-authorization", "cookie", or
+ * "set-cookie", the full header value is written verbatim to the JSON
+ * eve.log.  An attacker or insider with log access obtains plaintext
+ * Bearer tokens, Basic auth credentials, session cookies, and proxy
+ * passwords.  The default suricata.yaml.in explicitly shows Authorization
+ * as an example custom field with no redaction warning.
+ *
+ * Fix: EveHttpLogJSONHeaders() checks each header name against a static
+ * credential denylist before writing the value.  Matching headers emit
+ * "[REDACTED]" instead of the raw header value.  Non-credential headers
+ * are unaffected.
+ *
+ * This Java test models the patched and unpatched selection logic as plain
+ * string functions, confirms correctness, and demonstrates the exposure.

+Target: https://github.com/OISF/suricata (depth=1)
+Language: C
+Date: 2026-03-31
+Scanned by: agent blackops
+
+MOAD-0001 CWE-407 (linear scan in loop):
+  CLEAN. Suricata uses bitarrays (SigGroupHead sig_array), hash tables
+  (SigGroupHeadHashTable, MpmInitHash, THashLookupFromHash with HRLOCK),
+  and red-black trees (TCPSEG, SBB) throughout hot paths. Merge-sort
+  (O(N log N)) is used for signature ordering. No O(N^2) per-packet path
+  found. The probing parser port list scan is O(P) with P < 50 entries.
+
+MOAD-0002 Intertangle:
+  CLEAN. Subsystems are cleanly separated. The detection engine uses a
+  per-tenant DetectEngineCtx. App-layer parsers run in their own context.
+  Global registration lists (g_app_inspect_engines etc.) are write-once
+  at startup and read-only thereafter. No god object coupling independent
+  subsystems through shared mutable state.
+
+MOAD-0003 Leaked Context:
+  CLEAN. All thread_local variables hold thread-scoped data:
+  thread_pkt_pool (packet pool), t_thread_name (thread identifier),
+  pcap_file_thread (output file handle), tcp_pool_cache (segment pool),
+  locks[] (lock profiling). None holds request-scoped identity that
+  could leak across flow or packet boundaries.
+
+MOAD-0004 CWE-312 (credentials logged verbatim):
+  DEFECT — see defects/suricata-0001/ for patch and test.
+  EveHttpLogJSONHeaders() in src/output-json-http.c logs all header values
+  verbatim when dump-all-headers is enabled or when a custom field list
+  includes credential headers. The default suricata.yaml.in shows
+  "Authorization" as a custom field example with no warning. At runtime:
+  Authorization (Bearer/Basic tokens), Proxy-Authorization, Cookie
+  (session tokens), and Set-Cookie values appear in eve.log in cleartext.
+
+MOAD-0005 Thundering Herd:
+  CLEAN. THashLookupFromHash acquires a per-row HRLOCK before any read
+  or write. THashAdd uses the same HRLOCK. No get+null+compute+put
+  race window exists. Flow hash (FlowGetFlowFromHash) also uses per-bucket
+  mutex (FBLOCK_LOCK). No concurrent cache unsynchronized race found.
