AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-18127 affects Ivanti Endpoint Manager versions prior to 2024 SU7. It involves external control of a filename in the Core component, which can be exploited by a remote authenticated attacker to gain full write access to an S3 bucket used for session recording storage. This vulnerability is classified under CWE-73 (External Control of File Name or Path) and has a CVSS 3.1 base score of 7.7, reflecting high impact on data integrity. No known exploits in the wild have been reported, and the product is not a cloud service.
Potential Impact
An authenticated remote attacker can manipulate filenames to gain full write control over an S3 bucket configured for session recording storage. This could allow unauthorized modification or insertion of data into the bucket, compromising the integrity of session recordings. There is no impact on confidentiality or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions before 2024 SU7, upgrading to version 2024 SU7 or later is likely the intended remediation once officially released. Until then, restrict authenticated access to trusted users and monitor for suspicious activity related to session recording storage.
