{"id":"CVE-2024-29190","aliases":["GHSA-wfgj-wrgh-h3r3","PYSEC-2024-257","PYSEC-2026-1677"],"url":"https://o3.security/vulnerability/CVE-2024-29190","summary":"MobSF SSRF Vulnerability on assetlinks_check(act_name, well_knowns)","details":"### Summary\nWhile examining the \"App Link assetlinks.json file could not be found\" vulnerability detected by MobSF, we, as the Trendyol Application Security team, noticed that a GET request was sent to the \"/.well-known/assetlinks.json\" endpoint for all hosts written with \"android:host\". In the AndroidManifest.xml file.\n\nSince MobSF does not perform any input validation when extracting the hostnames in \"android:host\", requests can also be sent to local hostnames. This may cause SSRF vulnerability.\n\n### Details\nExample <intent-filter structure in AndroidManifest.xml:\n\n```\n<intent-filter android:autoVerify=\"true\">\n<action android:name=\"android.intent.action.VIEW\" />\n<category android:name=\"android.intent.category.DEFAULT\" />\n<category android:name=\"android.intent.category.BROWSABLE\" />\n<data android:host=\"192.168.1.102/user/delete/1#\" android:scheme=\"http\" />\n</intent-filter>\n```\n\n\nWe defined it as android:host=\"192.168.1.102/user/delete/1#\". Here, the \"#\" character at the end of the host prevents requests from being sent to the \"/.well-known/assetlinks.json\" endpoint and ensures that requests are sent to the endpoint before it.\n\n\n<img width=\"617\" alt=\"image\" src=\"https://github.com/MobSF/Mobile-Security-Framework-MobSF/assets/150332295/c570cb00-e947-4ad7-af80-26d46c0ad3f7\">\n\n\n### PoC\nhttps://drive.google.com/file/d/1nbKMd2sKosbJef5Mh4DxjcHcQ8Hw0BNR/view?usp=share_link\n\n\n### Impact\nThe attacker can cause the server to make a connection to internal-only services within the organization's infrastructure.","published":"2024-03-22T22:12:22.561Z","modified":"2026-08-12T03:51:35.749156632Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"mobsfscan","fixedVersion":"0.3.8"}],"fix":{"url":"https://github.com/MobSF/Mobile-Security-Framework-MobSF/commit/5a8eeee73c5f504a6c3abdf2a139a13804efdb77","label":"MobSF/Mobile-Security-Framework-MobSF@5a8eeee"},"references":[{"type":"WEB","url":"https://drive.google.com/file/d/1nbKMd2sKosbJef5Mh4DxjcHcQ8Hw0BNR/view?usp=share_link"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/29xxx/CVE-2024-29190.json"},{"type":"ADVISORY","url":"https://github.com/MobSF/Mobile-Security-Framework-MobSF/security/advisories/GHSA-wfgj-wrgh-h3r3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-29190"},{"type":"FIX","url":"https://github.com/MobSF/Mobile-Security-Framework-MobSF/commit/5a8eeee73c5f504a6c3abdf2a139a13804efdb77"},{"type":"WEB","url":"https://github.com/MobSF/mobsfscan/commit/61fd40b477bbf9d204eb8c5a83a86c396d839798"},{"type":"WEB","url":"https://github.com/MobSF/mobsfscan/commit/cd01b71770a6e56c1c71b0e5f454e7b6c9c64ef4"},{"type":"PACKAGE","url":"https://github.com/MobSF/Mobile-Security-Framework-MobSF"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/mobsf/PYSEC-2024-257.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:35.749156632Z"}}
