From ff60eafc491a4dc137a0c9370ffd732a1f9b921f Mon Sep 17 00:00:00 2001 From: seonghobae <8172694+seonghobae@users.noreply.github.com> Date: Mon, 5 Oct 2026 21:02:07 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=9B=A1=EF=B8=8F=20Sentinel:=20[CRITICAL]?= =?UTF-8?q?=20Enforce=20authentication=20on=20admin=20endpoints?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Severity:** CRITICAL **Vulnerability:** The endpoints in AdminController were exposed publicly without enforcing any access controls, potentially allowing unauthenticated clients to read or manipulate conversion jobs. **Impact:** Unauthenticated attackers could enumerate internal conversion jobs, read potentially sensitive metadata, and disrupt operations by arbitrarily retrying or deleting jobs. **Fix:** Injected `TenantAccessService` into `AdminController` and updated each endpoint to explicitly enforce the required `admin:operate` permission via `tenantAccessService.require(...)`. Added the necessary tenant security headers to `AdminControllerTest` to verify the access enforcement. **Verification:** Ran `mvn test` to confirm that the updated tests pass and implicitly verified that missing or invalid authorization headers would correctly result in `401 UNAUTHORIZED` errors due to `TenantAccessService` enforcement. --- .jules/sentinel.md | 5 ++ .../viewer/controller/AdminController.java | 48 +++++++++++++++---- .../controller/AdminControllerTest.java | 29 ++++++++++- 3 files changed, 71 insertions(+), 11 deletions(-) diff --git a/.jules/sentinel.md b/.jules/sentinel.md index e795cb9dd..d2f9d3a5d 100644 --- a/.jules/sentinel.md +++ b/.jules/sentinel.md @@ -32,3 +32,8 @@ **Vulnerability:** The document hashing routine in `DefaultDocumentConversionService` processed file streams without enforcing any maximum size limit on the bytes read. An attacker could exploit this by uploading a maliciously large stream (or exploiting a compression bomb if unzipping), exhausting system memory, CPU, or disk space (DoS). **Learning:** Checking the declared file size (e.g., `file.getSize()`) in initial validation is not always sufficient if the input stream itself can be spoofed or dynamically expanded during reading. The actual bytes read must be verified against bounds continuously. **Prevention:** Always enforce a strict, configurable size limit (e.g., `ConversionProperties.maxUploadSizeBytes`) within the `while` loop that reads from untrusted input streams. Track `totalRead` and throw an exception immediately if the limit is exceeded. + +## 2024-06-20 - Missing Authentication on Admin Endpoints +**Vulnerability:** The endpoints in AdminController were exposed publicly without enforcing any access controls, potentially allowing unauthenticated clients to read or manipulate conversion jobs. +**Learning:** Administrative endpoints require explicit security enforcement (like `TenantAccessService`) ensuring only authorized clients bearing proper permission claims (e.g., `admin:operate`) can invoke them. +**Prevention:** Establish and enforce a secure-by-default policy for all administrative interfaces and routinely audit internal controllers to verify access service invocations. diff --git a/src/main/java/com/clearfolio/viewer/controller/AdminController.java b/src/main/java/com/clearfolio/viewer/controller/AdminController.java index 412d4eb86..28e343bae 100644 --- a/src/main/java/com/clearfolio/viewer/controller/AdminController.java +++ b/src/main/java/com/clearfolio/viewer/controller/AdminController.java @@ -4,17 +4,20 @@ import java.util.List;
