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. + +## 2026-08-29 - ν™˜κ²½λ³€μˆ˜λ₯Ό ν†΅ν•œ μ‹œν¬λ¦Ώ μ£Όμž… 취약점 제거 +**Vulnerability:** `application-buyer-demo.yml`μ—μ„œ λŸ°νƒ€μž„ μ‹œν¬λ¦Ώ(artifact-token HMAC secret, tenant-claims HMAC secret)이 μŠ€ν”„λ§ ν™˜κ²½λ³€μˆ˜ ν”Œλ ˆμ΄μŠ€ν™€λ”(`${ENV_VAR:}`)λ₯Ό 톡해 μ£Όμž…λ˜κ³  μžˆμ—ˆμŠ΅λ‹ˆλ‹€. μ΄λŠ” ν™˜κ²½λ³€μˆ˜κ°€ λŸ°νƒ€μž„ μ†ŒμŠ€λ‘œ μ‚¬μš©λ˜μ–΄ μ‹œν¬λ¦Ώμ΄ λ…ΈμΆœλ  수 μžˆλŠ” λ³΄μ•ˆ μœ„ν—˜μ„ μ΄ˆλž˜ν•©λ‹ˆλ‹€. +**Learning:** λŸ°νƒ€μž„ μ„€μ •μ΄λ‚˜ μ‹œν¬λ¦Ώμ„ `os.getenv()`λ‚˜ μŠ€ν”„λ§ ν™˜κ²½λ³€μˆ˜λ₯Ό 톡해 직접 μ½λŠ” 것은 μ•ˆμ „ν•˜μ§€ μ•ŠμŠ΅λ‹ˆλ‹€. μ‹œν¬λ¦Ώμ€ KV(Key-Value) λ ˆμ§€μŠ€νŠΈλ¦¬λ‚˜ DB 기반의 μ•”ν˜Έν™”λœ μ €μž₯μ†Œμ™€ 같이 μ•ˆμ „ν•œ μ†ŒμŠ€μ—μ„œ 가져와야 ν•˜λ©°, ν™˜κ²½λ³€μˆ˜λŠ” KV둜 데이터λ₯Ό μ „μ†‘ν•˜λŠ” μš©λ„λ‘œλ§Œ μ œν•œν•΄μ•Ό ν•©λ‹ˆλ‹€. +**Prevention:** ν™˜κ²½λ³€μˆ˜ ν”Œλ ˆμ΄μŠ€ν™€λ”λ₯Ό μ œκ±°ν•˜κ³  Spring Boot의 configtree 지원을 μ‚¬μš©ν•˜μ—¬ μ‹œν¬λ¦Ώμ„ λŸ°νƒ€μž„μ— 직접 λ‘œλ“œν•˜λ„λ‘ λ§ˆμ΄κ·Έλ ˆμ΄μ…˜ν•΄μ•Ό ν•©λ‹ˆλ‹€. μŠ€ν”„λ§ `@Value` μ• λ„ˆν…Œμ΄μ…˜μ—μ„œ 빈 λ¬Έμžμ—΄μ˜ λ””ν΄νŠΈ 값을 μ œκ±°ν•˜μ—¬ μ‹œμž‘ μ‹œ μ‹€νŒ¨ν•˜κ²Œ λ§Œλ“€λ©΄(fail-fast), λ³΄μ•ˆ 속성이 λˆ„λ½λ˜μ—ˆμ„ λ•Œμ˜ 취약점 방지에 도움을 μ€λ‹ˆλ‹€. diff --git a/branch_script.sh b/branch_script.sh new file mode 100644 index 000000000..09f2c0db8 --- /dev/null +++ b/branch_script.sh @@ -0,0 +1,10 @@ +git checkout -b sentinel/fix-secrets-injection +git add . +git commit -m "πŸ›‘οΈ Sentinel: [CRITICAL] Fix secrets injection vulnerability + +🚨 Severity: CRITICAL +πŸ’‘ Vulnerability: Runtime secrets were injected via environment variables using Spring placeholders, which risks exposing them. +🎯 Impact: Attackers could read sensitive HMAC and artifact token secrets if they gain access to the environment. +πŸ”§ Fix: Removed environment variable fallbacks and default empty strings from `@Value` annotations, enforcing KV-based config tree lookups. +βœ… Verification: Ran `mvn clean verify` to ensure tests pass with the fail-fast startup behavior. +" diff --git a/src/main/java/com/clearfolio/viewer/artifact/ArtifactLinkService.java b/src/main/java/com/clearfolio/viewer/artifact/ArtifactLinkService.java index 79a972e3d..bcee94fda 100644 --- a/src/main/java/com/clearfolio/viewer/artifact/ArtifactLinkService.java +++ b/src/main/java/com/clearfolio/viewer/artifact/ArtifactLinkService.java @@ -79,7 +79,7 @@ public class ArtifactLinkService { public ArtifactLinkService( ArtifactStore artifactStore, ArtifactLinkLedger artifactLinkLedger, - @Value("${clearfolio.artifact-token.secret:}") String configuredSecret) { + @Value("${clearfolio.artifact-token.secret}") String configuredSecret) { this(artifactStore, artifactLinkLedger, configuredSecret, Clock.systemUTC(), new SecureRandom());
