CISA adds iPhone bugs to its Known Exploited Vulnerabilities catalog

US CISA added three zero-day vulnerabilities affecting iPhones, Macs, and iPads to its Known Exploited Vulnerabilities catalog.

US Cybersecurity and Infrastructure Security Agency (CISA) added three zero-day vulnerabilities affecting iPhones, Macs, and iPads to its Known Exploited Vulnerabilities Catalog.

The three issues reside in the WebKit browser engine and are tracked as CVE-2023-32409, CVE-2023-28204, and CVE-2023-32373.

Below are the details of the threat vulnerabilities that were recently addressed by Apple:

CVE-2023-32409 – Apple Multiple Products WebKit Sandbox Escape Vulnerability. Apple iOS, iPadOS, macOS, tvOS, watchOS, and Safari WebKit contain an unspecified vulnerability that can allow a remote attacker to break out of the Web Content sandbox.
CVE-2023-28204 – Apple Multiple Products WebKit Out-of-Bounds Read Vulnerability. Apple iOS, iPadOS, macOS, tvOS, watchOS, and Safari WebKit contain an out-of-bounds read vulnerability that may disclose sensitive information.
CVE-2023-32373 – Apple Multiple Products WebKit Use-After-Free Vulnerability. Apple iOS, iPadOS, macOS, tvOS, watchOS, and Safari WebKit contain a use-after-free vulnerability that leads to code execution.

“Apple is aware of a report that this issue may have been actively exploited,” reads the advisory [1, 2] published by the tech giant.

The company released iOS and iPadOS 16.5, tvOS 16.5, watchOS 9.5, Safari 16.5, and macOS Ventura 13.4 to address the issues.

Apple initially addressed both CVE-2023-28204 and CVE-2023-32373 with the Rapid Security Response (RSR) patches for iOS 16.4.1 and macOS 13.3.1 on May 1.

Since the beginning of 2023, the company addressed a total of six zero-day vulnerabilities exploited in attacks in the wild.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts recommend also private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix this flaw by June 12, 2023.

U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the following three new issues to its Known Exploited Vulnerabilities Catalog:
