Vulnerability details

Deserialization of Untrusted Data vulnerability in Apache Lucene.Net.Replicator. This issue affects Apache Lucene.NET's Replicator library: from 4.8.0-beta00005 through 4.8.0-beta00016. An attacker that can intercept traffic between a replication client and server, or control the target replication node URL, can provide…

addresses: CWE-502

Validates or rejects untrusted serialized data before deserialization occurs.

addresses: CWE-502

Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.

addresses: CWE-502

Integrity verification of serialized information can detect tampering before deserialization occurs.

addresses: CWE-502

Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
