JetBrains has issued a warning to its customers regarding a significant security flaw detected in its TeamCity On-Premises software, known as CVE-2024-23917. This vulnerability poses a critical risk as it allows unauthenticated attackers with HTTP(S) access to potentially gain administrative control over susceptible instances. The flaw impacts all TeamCity On-Premises versions from 2017.1 through 2023.11.2, emphasizing the wide-ranging implications for users. To address the issue, JetBrains advises users to update their servers to version 2023.11.3 or apply a security patch plugin promptly.
Despite the severity of the vulnerability, there is currently no evidence suggesting that it has been exploited in the wild. However, given the potential consequences, JetBrains urges users to take immediate action to mitigate the risk, especially if their servers are publicly accessible over the internet.
