An unrestricted file upload vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to write dangerous files.
AnalysisAI
An unrestricted file upload vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to write dangerous files. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Deserialization of Untrusted Data (CWE-502), which allows attackers to execute arbitrary code through malicious serialized objects. An unrestricted file upload vulnerability exists in Ivanti Avalanche before 6.3.3 allows an attacker with access to the Inforail Service to write dangerous files. Affected products include: Ivanti Avalanche. Version information: before 6.3.3.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid deserializing untrusted data. Use safe serialization formats (JSON). Implement integrity checks and type allowlists.
