SAP Note 3140564 addresses "[CVE-2022-22528] Information Disclosure in SAP Adaptive Server Enterprise" to prevent information disclosure with a medium risk for exploitation.

Risk specification

SAP Adaptive Server Enterprise allows an authenticated attacker to exploit an issue with the ASE installer and the attacker might be able to execute malicious Windows binaries that may lead to privilege escalation on the local system.

Solution

The issue is resolved by a correction PATH environment variable in the SAP ASE installer Circumstances exist that prevent the timely installation of a patch provided by the manufacturer. In such cases, you may consider applying the suggested workaround as a temporary or compensating mitigation: "Please assess the workaround applicability for your SAP landscape prior to implementation. SAP strongly recommends you apply the corrections outlined in the security note, which can be done in lieu of the workaround or after the workaround is implemented. In case you are using the affected versions then either manually remove SYBASE-related entry from system %PATH% environment variable, and source SYBASE.bat before running ASE utilities or update system %PATH% environment variable to appending SYBASE entries instead of prepending.".

The advisory is valid for
