CVE-2024-30041 Overview
CVE-2024-30041 is a spoofing vulnerability affecting the Microsoft Bing Search application on iOS. The flaw allows a network-based attacker to present misleading content to users, provided the target interacts with attacker-controlled input. Microsoft published the advisory through the Microsoft Security Response Center on May 14, 2024. The issue maps to [CWE-693] Protection Mechanism Failure, indicating that a security control intended to prevent spoofing was bypassed or absent. No public exploit code is available, and CISA has not added this CVE to the Known Exploited Vulnerabilities catalog.
Critical Impact
An attacker can spoof trusted content within the Bing Search iOS app, enabling phishing and social engineering attacks that abuse user trust in the Bing brand.
Affected Products
- Microsoft Bing Search for iOS (iPhone OS)
- All versions prior to the Microsoft-issued fix referenced in the MSRC advisory
- Deployments distributed through the Apple App Store

Technical Details for CVE-2024-30041
Vulnerability Analysis
CVE-2024-30041 is a spoofing weakness in the Microsoft Bing Search iOS application. Exploitation requires user interaction, and the attacker must deliver a crafted link or content payload over the network. Successful exploitation impacts confidentiality and integrity at a limited scope, without affecting availability. Microsoft classifies the flaw under [CWE-693] Protection Mechanism Failure, meaning a control designed to prevent content spoofing did not function as intended. The vulnerability enables an adversary to present content that appears to originate from Bing or a trusted source, which supports phishing and credential-harvesting scenarios.
Root Cause
Microsoft has not published detailed technical root-cause information for CVE-2024-30041. Based on the CWE-693 classification, the underlying issue is a missing or ineffective safeguard within the Bing iOS client. The safeguard was expected to validate rendered content, URL context, or trust indicators before display. When that safeguard fails, the application renders attacker-supplied content in a manner indistinguishable from legitimate Bing responses.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker crafts a URL, search result, or in-app content payload and delivers it to a target through email, messaging, or a compromised web page. When the user opens the payload in the Bing Search iOS app, the application renders spoofed content in a trusted context. This can facilitate phishing pages, fake login prompts, or misleading search results that direct users to attacker-controlled resources.
No verified proof-of-concept code has been published for CVE-2024-30041. Refer to the Microsoft Security Update Guide for authoritative technical details.
Detection Methods for CVE-2024-30041
Indicators of Compromise
- Mobile device telemetry showing Bing Search iOS app rendering content from unexpected external domains
- User reports of suspicious login prompts, credential requests, or brand-impersonation content within the Bing app
- Outbound network connections from iOS devices to newly registered domains following clicks on Bing search results
Detection Strategies
- Inspect mobile device management (MDM) inventory for outdated Bing Search app versions on iOS fleets
- Correlate proxy or DNS logs for iOS user agents accessing typosquatted or brand-impersonation domains reached via Bing
- Monitor phishing-report queues for user submissions referencing content displayed inside the Bing mobile app
Monitoring Recommendations
- Enable mobile threat defense telemetry to capture URL rendering and redirect chains initiated by the Bing app
- Track App Store update compliance for Microsoft-published applications across managed iOS devices
- Alert on user credential submissions to domains that do not match Microsoft or expected partner infrastructure
How to Mitigate CVE-2024-30041
Immediate Actions Required
- Update Microsoft Bing Search for iOS to the latest version available in the Apple App Store
- Enforce automatic app updates through MDM policy for all managed iOS devices
- Communicate phishing awareness guidance to users, emphasizing verification of login prompts inside mobile search apps
Patch Information
Microsoft addressed CVE-2024-30041 through an update to the Bing Search iOS application. Consult the Microsoft Security Update Guide for the fixed version and deployment notes. Because the app is distributed through the Apple App Store, remediation is applied by installing the current release rather than a traditional patch package.
Workarounds
- Restrict use of the Bing Search iOS app on managed devices until the patched version is confirmed installed
- Route mobile search traffic through an enterprise secure web gateway that blocks known phishing domains
- Advise users to open links from search results in a hardened browser rather than in-app views
# Example MDM query to identify Bing Search iOS app versions across managed devices
# Replace with your MDM vendor's syntax (Intune, Jamf, Workspace ONE, etc.)
