NVD description

An issue was discovered in ownCloud owncloud/core before 10.13.1. An attacker can access, modify, or delete any file without authentication if the username of a victim is known, and the victim has no signing-key configured. This occurs because pre-signed URLs can be accepted even when no signing-key is configured for the owner of the files. The earliest affected version is 10.6.0.

7.8/ 10 priority

    🚨 ownCloud CVE-2023-49105 aktif olarak istismar ediliyor! CVSS 9.8'lik WebDAV authentication bypass açığı 2023'ten beri biliniyor ve Aralık 2023'te public PoC'si yayınlandı. ownCloud 10.6.0–10.13.0 sürümlerini etkileyen açık 10.13.1'de yamalanmıştı. Buna rağmen saldırganlar, hala savunmasız olan bir ownCloud örneğinde geçerli kullanıcı adlarını ve boş signing secret'ı kullanarak sahte pre-signed WebDAV URL'leri oluşturdu ve kimlik doğrulaması olmadan dosyalara erişti. Saldırıda Filipinler'deki bir nükleer araştırma kuruluşundan yaklaşık 372 MB veri çalındı. CISA bu olaydan sonra CVE-2023-49105'i KEV kataloğuna ekledi.

    Post summary

    The post reports that CVE‑2023‑49105, a WebDAV authentication bypass in ownCloud, is actively being exploited in the wild, despite a published PoC and a patch in version 10.13.1, culminating in a significant data breach of a Philippine nuclear research organization.

    Post summary

    Multiple CVEs are confirmed actively exploited in the wild—PaperCut zero-day bypassing its first patch, Citrix NetScaler RCE with a same-day CISA deadline, and nine new CISA KEV entries—accompanied by observed credential-harvesting via exposed LLM gateways and the TerminalFix multistage campaign. Patches and workarounds exist for most disclosed vulnerabilities, but legacy unpatched systems remain primary attack vectors.

    Active Exploitation

    🚨 A three-year-old flaw reportedly opened the door to sensitive nuclear-agency data. http://Hunt.io uncovered infrastructure documenting an intrusion against a Philippine nuclear research body. The operation exploited CVE-2023-49105 in ownCloud, using pre-signed URLs generated with an empty signing secret to retrieve files over WebDAV without authentication. ⚠️ A recovered CSV referenced roughly 9 GB of stolen material. ⚠️ Exposed content reportedly included research, personnel and credential-related records. ⚠️ http://Hunt.io assessed targeted collection with medium confidence but did not attribute it to a named group. Security teams should: ✅ Upgrade ownCloud to 10.13.3 or apply the relevant patch. ✅ Configure a strong signing key for pre-signed URLs. ✅ Rotate exposed credentials and invalidate sessions. ✅ Hunt for suspicious PROPFIND enumeration and mass downloads. ✅ Reduce the public exposure of sensitive collaboration systems. 🚀 Join Cert‑IX Early Access: https://cert-ix.com/early-access 🔎 Read the complete analysis: https://blog.cert-ix.com/articles/exploiting-legacy-flaws-the-fallout-at-the-philippines-nuclear-agency-mtjxi66f #CertIX #CriticalInfrastructure #NuclearSecurity #OwnCloud #CVE202349105 #ThreatHunting #VulnerabilityManagement #CyberExposureManagement #CTEM
