Many macOS and iOS functions have been open to a vulnerability in CocoaPods, an open-source dependency supervisor, E.V.A. Info Safety revealed on July 1. The vulnerability has been patched since EVA first found it, and no assaults have occurred which might be conclusively associated to it.
Nonetheless, the case is fascinating as a result of the vulnerability stayed unnoticed for therefore lengthy and highlighted how builders must be cautious with open-source libraries. The vulnerability is an efficient reminder for builders and DevOps groups to examine whether or not any of their organizations’ gadgets is likely to be affected.
“Thousands of applications and millions of devices” might have been impacted downstream, E.V.A. mentioned. The safety staff says they discovered weak CocoaPods pods in “the documentation or terms of service documents of applications provided by Meta (Facebook, Whatsapp), Apple (Safari, AppleTV, Xcode), and Microsoft (Teams); as well as in TikTok, Snapchat, Amazon, LinkedIn, Netflix, Okta, Yahoo, Zynga, and many more.”
E.V.A. reported the vulnerability to CocoaPods in October 2023, at which level it was patched.
“The CocoaPods team responded responsibly and swiftly to the vulnerabilities once disclosed,” E.V.A. Info Safety wrote.
Vulnerabilities originated in CocoaPods
CocoaPods is a dependency supervisor for Swift and Goal-C initiatives, and it verifies the legitimacy of open-source elements. E.V.A. Info Safety wasn’t initially trying to find vulnerabilities in CocoaPods; as an alternative, the staff found them when crimson teaming for a buyer.

E.V.A. reported a number of causes for the vulnerabilities. First, CocoaPods migrated from GitHub to a “trunk” server in 2014, however the pod homeowners wanted to manually reclaim their spots. A few of them didn’t, leaving 1,866 “orphaned” pods that sat untouched for the following 10 years. Anybody might e-mail CocoaPods to assert these pods, which might have allowed attackers to inject malicious content material.
Second, attackers might run malicious code on the “trunk” server itself by exploiting an insecure e-mail verification workflow. From there, they may manipulate or change packages downloaded from that server.
Third, attackers might steal account verification tokens by spoofing an HTTP header and making the most of misconfigured e-mail safety instruments. From there, they may use that token to vary packages on the CocoaPods server, which might doubtlessly result in provide chain and zero-day assaults.
What builders and DevOps groups can do to mitigate the CocoaPods vulnerabilities
The CocoaPods vulnerabilities are a very good reminder to builders and DevOps groups to not overlook about dependency managers, which might be a possible weak hyperlink in provide chain safety. To deal with the CocoaPods vulnerabilities, builders and DevOps groups ought to double examine the open-source dependencies used of their utility code.
E.V.A. advised:
- In case you’re utilizing software program that depends on orphaned CocoaPods packages, preserve your podfile.lock file synchronized with all CocoaPods builders to make sure everyone seems to be on the identical model of the packages.
- Assessment dependency lists and package deal managers utilized in your functions.
- Validate checksums of third-party libraries.
- Carry out periodic scans of exterior libraries, particularly CocoaPods, to detect malicious code or suspicious modifications.
- Hold software program up to date.
- Restrict use of orphaned or unmaintained CocoaPods packages.
- Be cautious of the potential exploitation of extensively used dependencies like CocoaPods.
