Conversation
Critical fixes: 1. RCE via install script download (commands.rs) - Download script to temp file first - Verify SHA256 checksum before execution - Prevents MITM attacks on install.sh 2. Command injection in exec_login (ssh.rs) - Sanitize target_bin to allow only safe characters - Shell-quote commands for safe interpolation - Replace unsafe eval with pipe to stdin Added sha2 dependency for checksum verification.

感谢这个 PR!PATH 修复的部分解决了一个真实存在的 macOS 问题,写得很不错。不过安全相关的改动有几个问题,建议拆分处理。
✅ path_fix.rs — 很好,愿意合入
macOS 从 Finder/Dock 启动时拿不到 shell PATH 是个真实痛点,这个模块的实现很扎实:
- NVM/FNM 版本探测逻辑完善,有 alias/default 回退
- PATH 去重 prepend 逻辑正确
- 测试覆盖到位
小建议:unsafe { env::set_var } 虽然在 main() 线程启动前调用是安全的,但可以加个注释说明为什么这里是 safe 的。
❌ 安全相关改动 — 建议移除
1. SHA256 校验值是空字符串的哈希
const INSTALL_SCRIPT_SHA256: &str = "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855";这是 SHA256("") 的结果(空字符串哈希),实际运行时会始终拒绝真正的 install.sh,直接导致升级功能完全不可用。
2. 固定哈希的方案本身不可行
openclaw 的 install.sh 会随版本更新变化,如果我们 pin 住哈希值,每次上游脚本更新都需要 ClawPal 同步发版,造成不必要的耦合。而且 curl | bash 走的是 HTTPS,传输层已经有完整性保护。
3. exec_login 的注入防护解决的是不存在的问题
传入 exec_login 的命令全部由我们自己的代码构造,不涉及用户输入,不存在注入风险。另外:
shell_quote函数在 diff 中被引用但未定义eval "$(fnm env)"改为{ fnm env; } | . /dev/stdin降低了可移植性,eval是 fnm 官方推荐的用法
建议
请把 PR 拆成两个:
path_fix.rs模块 — 可以直接合入(或小改后合入)- 安全改动 — 建议先讨论威胁模型再决定是否需要
|
已经把 PATH 修复的 commit ( 安全相关的 commit 暂时没有合入,原因见上面的 review。如果你觉得有需要可以继续讨论威胁模型,或者单独开一个 PR。 |
|
感谢详细 review,也感谢已经把 path_fix commit cherry-pick 到 main。release notes 里也加了致谢,感谢你们这么快处理。 安全相关改动我接受拆分处理,这个 PR 不再继续推进该部分。你指出的空 SHA256 常量问题是有效 bug,会导致升级流程不可用,这点我认领;在当前线程里继续修补这些改动,确实不如先收敛。 固定哈希与 exec_login 改动是否值得引入,需要先在明确威胁模型下讨论。我认同目前这部分论证还不够完整,尤其是保护目标、维护成本和兼容性 tradeoff 还没有定义清楚。 我会单独开一个威胁模型讨论/issue,整理本地升级和远程升级的保护目标、攻击面(传输、脚本来源、远端 shell 执行)、信任边界,以及可接受的维护成本/兼容性约束,再决定是否提交独立 PR。再次感谢 review 和 cherry-pick。 |

This PR appears resolved — the path_fix.rs commit was already cherry-picked to main by the repo owner, and the security-related changes were declined pending a separate threat model discussion. Both parties agreed to close out the security portion.
No further action needed from reviewers. The contributor mentioned they'll open a separate issue for the threat model discussion if they want to pursue the security hardening.

PR #9 Formal Review — fix/critical-security-vulnerabilities
Following up with a formal review decision since this hasn't been closed yet.
🔴 BS: INSTALL_SCRIPT_SHA256 is SHA256("") — the empty-string hash
const INSTALL_SCRIPT_SHA256: &str = "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855";This is the well-known SHA-256 of an empty input. Any non-empty install.sh will always fail the checksum check, making run_openclaw_upgrade permanently broken for all users. The same hardcoded hash is also embedded in the remote exec_login shell command, so remote upgrade is equally broken.
Beyond this specific bug, zhixianio already explained in detail why a pinned-hash scheme doesn't work for a frequently-updated install script — each upstream change would require a coordinated ClawPal release just to bump the constant. The PR also has merge conflicts at this point.
✅ path_fix.rs — still good
The macOS PATH-fix module itself is solid (as noted in earlier reviews) and was already cherry-picked to main.
Recommendation: The security-hardening portion needs a proper threat model discussion (see repo owner's earlier comment) before any implementation. Suggest closing this PR and opening a separate issue to track the upgrade-integrity work if you'd like to continue.

BS: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 is SHA256("") — the hash of an empty string. Every real install.sh will fail this check, permanently breaking the upgrade command. This needs to be a real hash (or the pinned-hash approach needs to be reconsidered entirely).
背景
macOS 上通过 DMG 安装后,从 Finder / Dock 启动 ClawPal 时,应用进程可能拿不到 shell 的 PATH,导致
openclaw(以及依赖的node)无法被发现。此前启动阶段仅调用
fix_path_env::fix(),且错误被静默忽略,缺少失败时的补救逻辑。改动内容
src-tauri/src/path_fix.rs(macOS PATH 修复模块)ensure_tool_paths()(非 macOS 平台 no-op)fix_path_env::fix()改为记录成功/失败日志openclaw或node缺失时,探测常见目录并补全 PATH~/Library/Application Support/fnm)路径探测openclaw/node最终发现结果到~/.clawpal/logs/app.log验证
cargo test path_fix --lib✅cargo build --lib✅建议手工验证(macOS)
