From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Kiran Ramachandra Date: Wed, 5 Jun 2024 21:03:33 +0000 Subject: [PATCH] DO NOT MERGE Ignore - Sanitized uri scheme by removing scheme delimiter Initially considered removing unsupported characters as per IANA guidelines, but this could break applications that use custom schemes with asterisks. Instead, opted to remove only the "://" to minimize disruption Bug: 261721900 Test: atest FrameworksCoreTests:android.net.UriTest No-Typo-Check: The unit test is specifically written to test few cases, string "http://https://" is not a typo (cherry picked from https://googleplex-android-review.googlesource.com/q/commit:1fd0421801c391dd619cafeeea8d379a9029074a) Merged-In: I88b1550a5d8b3dc0f6286e28899884025d059645 Change-Id: I88b1550a5d8b3dc0f6286e28899884025d059645 --- core/java/android/net/Uri.java | 6 +++++- core/tests/coretests/src/android/net/UriTest.java | 11 +++++++++++ 2 files changed, 16 insertions(+), 1 deletion(-) diff --git a/core/java/android/net/Uri.java b/core/java/android/net/Uri.java index 84fc4f78edc4..4446f09bc874 100644 --- a/core/java/android/net/Uri.java +++ b/core/java/android/net/Uri.java @@ -1380,7 +1380,11 @@ public abstract class Uri implements Parcelable, Comparable { * @param scheme name or {@code null} if this is a relative Uri */ public Builder scheme(String scheme) { - this.scheme = scheme; + if (scheme != null) { + this.scheme = scheme.replace("://", ""); + } else { + this.scheme = null; + } return this; } diff --git a/core/tests/coretests/src/android/net/UriTest.java b/core/tests/coretests/src/android/net/UriTest.java index 670aefd21d36..17a37831afdb 100644 --- a/core/tests/coretests/src/android/net/UriTest.java +++ b/core/tests/coretests/src/android/net/UriTest.java @@ -18,6 +18,7 @@ package android.net; import android.content.ContentUris; import android.os.Parcel; +import android.platform.test.annotations.AsbSecurityTest; import androidx.test.filters.SmallTest; @@ -88,6 +89,16 @@ public class UriTest extends TestCase { assertNull(u.getHost()); } + @AsbSecurityTest(cveBugId = 261721900) + @SmallTest + public void testSchemeSanitization() { + Uri uri = new Uri.Builder() + .scheme("http://https://evil.com:/te:st/") + .authority("google.com").path("one/way").build(); + assertEquals("httphttpsevil.com:/te:st/", uri.getScheme()); + assertEquals("httphttpsevil.com:/te:st/://google.com/one/way", uri.toString()); + } + @SmallTest public void testStringUri() { assertEquals("bob lee",
