adversarial stress test suites (902 total tests) - test_BufferStress: Overflow/underflow attacks on ByteBuffer, NaN/Inf/denorm floats, massive writes (100k entries), packed GUID fuzzing, bit operation edge cases, rapid clear/reuse cycles, partial reads - test_GameStress: NaN coordinate injection, integer overflow in damage formulas, degenerate armor/resist values, health oscillation boundaries, max uint32/int32 edge cases, distance triangle inequality verification - test_NetworkStress: Malformed packet payloads, truncated reads, oversized strings, packet header validation (size bounds), movement hack detection (NaN/Inf/speed/map bounds), chat sanitization (control chars, truncation), session key validation, cipher stress (100KB encrypt/decrypt), packet flood simulation (10k create/destroy cycles) All 902 tests pass in 5ms. https://claude.ai/code/session_01BASLpNitMR8fr4c1HUQHdP --- tests/CMakeLists.txt | 6 + tests/test_BufferStress.cpp | 458 +++++++++++++++++++++++++++++

d62efb5f31b9d5735a238f6793e4e70e6aadb593 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 25 Mar 2026 22:57:54 +0000 Subject: [PATCH 06/16] Add WoW 4.3.4 mock client and fix 5 server bugs found during testing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mock client (tests/mock_client.py): - Full WoW 4.3.4 protocol implementation: correct CMSG_AUTH_SESSION byte layout mirroring WorldSocket::HandleAuthSession() read order, BuiltNumberClient as uint16, packed account name length encoding - 6 normal mechanic tests: auth OK/unknown/wrong-build, char enum, ping-pong, 10 sequential pings - 17 adversarial tests: pre-auth opcodes, double auth, game packets before login, overflow pings, length mismatch, zero-body opcodes, 50x rapid auth cycle, 10x concurrent auth, 100 concurrent sessions, null GUID login, logout without login, 200 garbage opcodes, 1000 ping flood — all 23 tests pass, server stays alive throughout Server fixes: - WorldSocket::CloseSocket / handle_close: flush m_OutBuffer before closing so error responses (AUTH_UNKNOWN_ACCOUNT, etc.) actually reach the client instead of being silently dropped - WorldSocket::close: revert accidental flush added to wrong method - CharacterHandler::HandlePlayerLoginOpcode: reset m_playerLoading on ByteBufferException so empty-body CMSG_PLAYER_LOGIN can't permanently lock out the account from re-login - CharacterHandler::HandlePlayerLoginCallback: skip callback if session is no longer in loading state, preventing a stale async DB callback from kicking a freshly reconnected session - WorldSession::IsSocketClosed / World::RemoveSession: allow session replacement when the old session's socket is already closed but m_playerLoading is still true (client disconnected mid-character-load) https://claude.ai/code/session_01BASLpNitMR8fr4c1HUQHdP --- src/game/Server/WorldSession.cpp | 5 + src/game/Server/WorldSession.h | 2 + src/game/Server/WorldSocket.cpp

This is undefined behavior in C++ and silently produces 0 on common platforms. Added SafeUInt32FromFloat/SafeUInt32FromDouble helpers to Util.h that clamp to [0, UINT32_MAX] before casting. Applied the fix across 20+ locations in the server source where the same pattern existed: - Damage sharing (Unit.cpp) - Shield block calculation (Unit.cpp) - SetHealthPercent (Unit.cpp) - Combat rating damage reduction (Unit.cpp) - XP modifiers from auras (Player.cpp) - Quest/exploration XP with rate multipliers (Player.cpp) - Gold/loot drops with rate multipliers (Player.cpp, LootMgr.cpp) - Spell heal/damage percent-of-max-health (SpellAuras.cpp, SpellEffects.cpp) - Mana regen percent calculations (SpellAuras.cpp) - Group XP distribution (Group.cpp) - Creature health regen (Creature.cpp) - Durability repair costs (Player.cpp) All 902 tests now pass (was 900/902). https://claude.ai/code/session_01RLuCkH1nCbpmCxSo7xhUWL --- src/game/Object/Creature.cpp | 4 ++-- src/game/Object/LootMgr.cpp | 6 +++--- src/game/Object/Player.cpp | 20 ++++++++++---------- src/game/Object/Unit.cpp | 10 +++++----- src/game/WorldHandlers/Group.cpp | 2 +- src/game/WorldHandlers/SpellAuras.cpp | 10 +++++----- src/game/WorldHandlers/SpellEffects.cpp | 8 ++++---- src/shared/Utilities/Util.h | 17 +++++++++++++++++ tests/test_GameStress.cpp | 14 ++++++++++++-- 9 files changed, 59 insertions(+), 32 deletions(-) diff --git a/src/game/Object/Creature.cpp b/src/game/Object/Creature.cpp index 7ec66a5546..f53f8b52d8 100644 --- a/src/game/Object/Creature.cpp +++ b/src/game/Object/Creature.cpp @@ -919,11 +919,11 @@ void Creature::RegenerateHealth() float Spirit = GetStat(STAT_SPIRIT);

charset=UTF-8 Content-Transfer-Encoding: 8bit Vulnerabilities fixed: 1. CRITICAL — Memory exhaustion via m_addonSize (WorldSocket.cpp:903) Client could send m_addonSize=0xFFFFFFFF triggering a 4GB allocation. Fix: Cap addon data at ~1MB (0xFFFFF) and reject oversized packets. 2. HIGH — SQL injection in character rename (CharacterHandler.cpp:1228) HandleChangePlayerNameOpcodeCallBack used unescaped newname.c_str() directly in PExecute UPDATE query. The escaped_newname was prepared in the calling function but never passed to the callback. Fix: Escape newname before use in the UPDATE statement. 3. MEDIUM — Unescaped IP in ban-check SQL (WorldSocket.cpp:1035) GetRemoteAddress() was interpolated directly into a SQL query with '%s' format. While typically safe (ACE returns dotted-quad), IPv6 or proxy scenarios could allow injection. Fix: Escape the IP string before interpolation. 4. MEDIUM — No packet rate limiting (WorldSocket) No per-connection packet rate limit existed. Clients could flood the server with unlimited packets/sec, exhausting CPU and DB pool. Fix: Add 300 packets/sec rate limiter per connection with automatic disconnect on violation. Also: - Complete character3 schema (20+ missing tables that caused SQL errors under concurrent load: character_pet, mail, arena_team_member, etc.) - Update setup_mariadb.sql with all tables - Adjust concurrent char enum test threshold for rate limiting All 73 tests pass: 23 mock client + 20 DB exploit + 30 stress tests. https://claude.ai/code/session_01MBz1CHzmcaxAcLjKGGT6qN --- sql/setup_mariadb.sql | 224 ++++++++++++++++++++ src/game/Server/WorldSocket.cpp | 47 +++- src/game/Server/WorldSocket.h | 6 + src/game/WorldHandlers/CharacterHandler.cpp | 5 +- tests/test_mock_client_db_exploits.py | 5 +- 5 files changed, 280 insertions(+), 7 deletions(-) diff --git a/sql/setup_mariadb.sql b/sql/setup_mariadb.sql index 6b903ad857..fc56bc9eca 100644 --- a/sql/setup_mariadb.sql +++ b/sql/setup_mariadb.sql @@ -294,6 +294,230 @@ CREATE TABLE IF NOT EXISTS `guild_member` ( UNIQUE KEY `guid_key` (`guid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Documents the post-Patch 4.0.1 crushing-blow rules: - Level-difference rule (retained from 3.0.2): attacker must be 4+ levels above defender to crush. Raid bosses standardized to 3 levels above max-level players, so bosses can no longer crush. - Tank-stance uncrushable (new in 4.0.1): properly-spec'd tanks in their tanking stance/presence/form are uncrushable regardless of attacker level. Reference: https://www.wowhead.com/guide=4.0.1 9 tests across 3 sections (level rule, tank stance, non-tank sanity). Tests the reimplemented formula inside the test file per the existing framework convention. A future production PR will extract the crushing logic from Unit::RollMeleeOutcomeAgainst into a pure helper and wire this spec test to it. Suite: 938 -> 947 tests, all passing.

Changes: - Replace structural-only `_CanCrush` assertions with exact percentage assertions sourced from the canonical Blizzard formula: +4 levels (skill_diff 20) -> 25% +5 levels (skill_diff 25) -> 35% +6 levels (skill_diff 30) -> 45% +10 levels (skill_diff 50) -> 85% - Drop the `defenderIsProperTank` parameter and the three TankInStance_* tests. Verification against warcraft.wiki.gg/wiki/Crushing_blow shows there is no separate tank-stance uncrushable rule in 4.0+; the "effectively uncrushable" tank property is purely emergent from raid bosses being standardized to +3 levels (below the 4-level floor). Asserting tank-stance immunity was testing a non-existent mechanic. - Drop NonTankPlayer_HighDiff_CanCrush since the high-diff case is now covered more precisely by AttackerTenAbove_85Percent. - Update file header with the verified canonical references.

These tests are NOT fixing a bug; they lock in the spec to prevent future drift, in the same way the crushing-blow tests are paired with the mangosthree/server#106 fix. Canonical formula per Wowpedia / Warcraft Wiki / WoWWiki Archive: DR% = armor / (armor + K), capped at 75% K(L<60) = 400 + 85*L K(L>=60) = 467.5*L - 22167.5 Specific K values asserted at the 50% mark: 60: 5882.5 70: 10557.5 80: 15232.5 83: 16635 85: 17570 And the 75% cap is asserted at armor == 3 * K. Conflict noted in the file header: TC-Preservation's implementation adds an extra `+20*(L-80)` term in the level modifier for L > 80 (giving K=26070 at L=85), citing the client's Paperdollframe.lua. That file is the tooltip-display calculation and likely does not reflect server-side damage math. Multiple secondary sources document the no-kicker formula, which is what mangosthree implements. We follow the wiki consensus. Suite: 945 -> 954 tests, all passing.

The math we test here is the application step that runs after the DBC-driven rating lookup: damage_after = damage * (1 - reduction_pct / 100) with these documented behaviours: - 0% (no resilience) or negative input: damage unchanged - 100% reduction: damage zeroed - >100% reduction: clamped to zero, never negative - Zero damage in: zero damage out - Standard 10%/25%/50% reductions: linear math - Fractional reduction (33.3% on 100 damage): truncates to integer using uint32 arithmetic The rating-to-percent conversion itself (at L85: ~95.79 rating per 1%) is data-driven via gtCombatRatings.dbc and verified separately at runtime, not in these unit tests. Reference: TC-Preservation Unit::ApplyResilience -> GetCombatRatingDamageReduction. Production implementation in mangosthree is non-functional and will be ported on a separate branch.
