An unpatched security issue in the Travis CI API has left tens of 1000’s of developers’ consumer tokens uncovered to probable attacks, efficiently allowing danger actors to breach cloud infrastructures, make unauthorized code modifications, and initiate supply chain assaults.
“A lot more than 770 million logs of free tier users are readily available, from which you can simply extract tokens, secrets, and other qualifications affiliated with well known cloud provider suppliers these as GitHub, AWS, and Docker Hub,” scientists from cloud security agency Aqua stated in a Monday report.
Travis CI is a continuous integration service utilized to construct and exam application initiatives hosted on cloud repository platforms these kinds of as GitHub and Bitbucket.
The issue, previously noted in 2015 and 2019, is rooted in the actuality that the API permits obtain to historical logs in cleartext structure, enabling a malicious bash to even “fetch the logs that had been beforehand unavailable through the API.”
The logs go all the way back again to January 2013 and up right until May 2022, ranging from log figures 4,280,000 to 774,807,924, which are utilised to retrieve a exceptional cleartext log as a result of the API.
What is additional, even more analysis of 20,000 logs revealed as many as 73,000 tokens, access keys, and other qualifications associated with various cloud products and services like GitHub, AWS, and Docker Hub.
This is inspite of Travis CI’s attempts to rate-restrict the API and routinely filter out safe ecosystem variables and tokens from construct logs by exhibiting the string “[secure]” in their put.
One of the critical insights is that while “github_token” was obfuscated, 20 other versions of this token that followed a diverse naming conference โ together with github_key, gh_token, github_api_critical, and github_secret โ weren’t masked by Travis CI.
“Travis CI slowed down the velocity of API phone calls, which hinders the ability to query the API,” the scientists claimed. “In this scenario however, this was not enough. A proficient risk actor can uncover a workaround to bypass this.”
“On the other hand, combining the relieve of accessing the logs by way of the API, incomplete censoring, accessing ‘restricted’ logs, and a weak procedure for charge limiting and blocking entry to the API, coupled with a significant variety of possibly exposed logs, final results in a critical predicament.”
Travis CI, in reaction to the findings, has mentioned the issue is “by structure,” necessitating that buyers comply with most effective procedures to prevent leaking techniques in build logs and periodically rotate tokens and secrets and techniques.
The results are notably major in the wake of an April 2022 attack campaign that leveraged stolen OAuth consumer tokens issued to Heroku and Travis CI to escalate access to NPM infrastructure and clone pick out personal repositories.
