Vulnerabilities > CVE-2022-23605 - Improper Cross-boundary Removal of Sensitive Data vulnerability in Wire Wire-Webapp
Summary
Wire webapp is a web client for the wire messaging protocol. In versions prior to 2022-01-27-production.0 expired ephemeral messages were not reliably removed from local chat history of Wire Webapp. In versions before 2022-01-27-production.0 ephemeral messages and assets might still be accessible through the local search functionality. Any attempt to view one of these message in the chat view will then trigger the deletion. This issue only affects locally stored messages. On premise instances of wire-webapp need to be updated to 2022-01-27-production.0, so that their users are no longer affected. There are no known workarounds for this issue.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Windows ::DATA Alternate Data Stream An attacker exploits the functionality of Microsoft NTFS Alternate Data Streams (ADS) to undermine system security. ADS allows multiple "files" to be stored in one directory entry referenced as filename:streamname. One or more alternate data streams may be stored in any file or directory. Normal Microsoft utilities do not show the presence of an ADS stream attached to a file. The additional space for the ADS is not recorded in the displayed file size. The additional space for ADS is accounted for in the used space on the volume. An ADS can be any type of file. ADS are copied by standard Microsoft utilities between NTFS volumes. ADS can be used by an attacker or intruder to hide tools, scripts, and data from detection by normal system utilities. Many anti-virus programs do not check for or scan ADS. Windows Vista does have a switch (-R) on the command line DIR command that will display alternate streams.
