SAP Patches Critical Vulnerability in Business One Product

SAP released a hotfix for a critical-severity improper access control vulnerability in Business One product installation.

Enterprise software maker SAP this week announced the release of three new and three updated security notes as part of its November 2023 Security Patch Day.

Rated ‘hot news’, the highest rating in SAP’s notebook, the most important of the newly released security notes addresses a vulnerability in enterprise resource planning application Business One.

Tracked as CVE-2023-31403 (CVSS score of 9.6), the bug is described as an improper access control in the Business One product installation.

“The process allows anonymous users read and write access to the SMB shared folder. Affected components are Crystal Report (CR) shared folder, Traditional Mobile app (attachment path), RSP (log folder logic), Job Service and BAS (file upload folder),” enterprise application security firm Onapsis explains.

The security note provides a hotfix for Business One version 10.0 SP 2308 and customers on lower support package (SP) levels are advised to update to SP 2308 and apply the provided hotfix.

Both the remaining two new security notes that SAP released this week address medium-severity information disclosure issues impacting NetWeaver Application Server ABAP and ABAP Platform and NetWeaver AS Java Logon.

The most important of SAP’s updated security notes addresses a critical-severity missing authorization check flaw in CommonCryptoLib, which impacts multiple products from the software maker.

SAP initially patched the vulnerability in September 2023, warning that it could lead to complete compromise of the affected application, and has now updated the security note’s text with minor changes, Onapsis explains.

The remaining two updated security notes address medium-severity vulnerabilities in NetWeaver AS Java and in multiple Sybase products.

While SAP makes no mention of any of these vulnerabilities being exploited in attacks, customers are advised to apply the patches as soon as possible.
