  • CWE-520 - .NET Misconfiguration: Use of Impersonation
Summary
Iperius Backup 6.1.0 contains a privilege escalation vulnerability that allows low-privilege users to execute arbitrary programs with elevated privileges by creating backup jobs. Attackers can configure backup jobs to execute malicious batch files or programs before or after backup operations, which run with the privileges of the Iperius Backup Service account (Local System or Administrator), enabling privilege escalation and arbitrary code execution.

8.1 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
CWE
  • CWE-520 - .NET Misconfiguration: Use of Impersonation
Summary
IBM Langflow OSS 1.0.0 through 1.10.1 can allow an attacker to access another user's private vector documents by creating their own flow with matching Chroma persist_directory and collection_name values. The attacker receives exact victim content in their workflow output despite having no authorization to read the victim's flow. Additionally, the attacker can pollute the victim's collection by inserting their own documents into the shared namespace.
