US EditionThousands of Servers Exposed as MongoBleed Vulnerability Exploited
CISA mandates patching of MongoBleed, a CVSS 8.7 flaw exploited on over 87,000 internet-exposed MongoDB instances, threatening sensitive data exposure without forensic traces.
- On Dec. 26, after a public proof-of-concept surfaced, the Cybersecurity and Infrastructure Security Agency added the MongoBleed flaw to its known exploited vulnerabilities catalog as firms reported active exploitation.
- As a memory-leak vulnerability, MongoBleed lets unauthenticated attackers read server memory and could expose credentials or tokens, affecting many MongoDB builds since 2017.
- Censys and Shadowserver observed over 87,000 potentially vulnerable MongoDB instances, while Wiz found 42% of cloud environments contain at least one vulnerable instance; the flaw has a CVSS 8.7 rating, Ben Read said.
- Because memory-leak attacks leave little trace, defenders may have limited proof data was accessed, while holiday downtime and reduced capacity delay triage as VulnCheck tracks over a dozen public proof-of-concepts.
- MongoDB warned customers to upgrade soon, citing global exposures concentrated in China, the United States, Germany, France, Hong Kong, India and Singapore across releases since 2017.
