CVE-2019-11043
Buffer Overflow in PHP-FPM Enables Unauthenticated RCE on nginx Stacks

CVE-2019-11043 is a buffer overflow (CWE-120/CWE-787) in PHP's FastCGI Process Manager (PHP-FPM) affecting PHP 7.1.x before 7.1.33, 7.2.x before 7.2.24, and 7.3.x before 7.3.11. In certain FPM configurations — commonly web servers such as nginx that split PATH_INFO via fastcgi_split_path_info without validating that the requested PHP script exists — an unauthenticated remote attacker can send a crafted request that makes PHP-FPM write past allocated buffers into the space reserved for FCGI protocol data. This corruption of the FastCGI protocol state allows the attacker to execute arbitrary code with the privileges of the PHP-FPM worker on the hosting web server. Anyone running a vulnerable PHP-FPM behind an affected configuration is exposed, including Linux distribution packages (Ubuntu, Debian, Fedora, Red Hat Enterprise Linux, Red Hat Software Collections), Tenable.sc deployments, and QNAP NAS devices running vulnerable PHP. The flaw is being actively exploited in the wild — it is in CISA's KEV with known ransomware use (including campaigns such as NextCry targeting Nextcloud instances on Linux servers) — and a public proof-of-concept exploit exists, consistent with its 99.8% EPSS score.

Do: Upgrade PHP to 7.1.33, 7.2.24, 7.3.11 or later (or apply your distribution's/vendor's patched packages — CISA's KEV required action is to apply updates per vendor instructions; QNAP users should apply QNAP's released updates). As an interim mitigation, harden the nginx fastcgi_split_path_info configuration (prefix the regex with '^' and use try_files to confirm the script exists) or disable PATH_INFO where it is not needed. Prioritize internet-facing web servers, shared hosting, and QNAP/Nextcloud instances for patching and check them for compromise, given active ransomware exploitation.

DevOps firewall: How pre-configuring your cloud deployment can ensure compliance
Following the recent massive Capital One data breach, it’s clear that even some of the world’s largest and most respected companies working in the cloud are still vulnerable to compliance and security issues. In this case, federal prosecutors charged a Seattle woman with stealing more than 100 million credit applications. As the details of the attack became public, the Capital One AWS environment came under scrutiny.

Is the enterprise on the brink of a global web supply chain attack?
Ever since the Web development ecosystem evolved to the current paradigm of code reuse, companies have placed themselves too close to the abyss. Web supply chain attacks are a real security threat – and one which the enterprise is vastly unprepared for.

Keeping up with the evolving ransomware security landscape
Cybersecurity must always be a fluid practice, one that is designed to meet novel threats and constantly upgraded and evaluated.

The nastiest ransomware, phishing and botnets of 2019
Webroot released its annual Nastiest Malware list, shedding light on 2019’s worst cybersecurity threats. From ransomware strains and cryptomining campaigns that delivered the most attack payloads to phishing attacks that wreaked the most havoc, it’s clear that cyber threats across the board are becoming more advanced and difficult to detect.

Want to overcome patching challenges once and for all? Automation is the key
The cybersecurity threatscape in the UK is extremely complex and sophisticated. It is no longer a question of whether a cyberattack will occur, but when; according to a recent Beaming report, UK businesses faced cyberattacks every 50 seconds in the second quarter of 2019.

Examining security process maturity in 400 organizations
There’s an overall failure in maturity of security processes of over 400 organizations in industries ranging from e-commerce, retail and payment processor to telecommunications, petroleum and more, a SecureTrust report reveals.

Majority of 2019 breaches were the result of unapplied security patches
Despite a 24% average increase in annual spending on prevention, detection and remediation in 2019 compared with 2018, patching is delayed an average of 12 days due to data silos and poor organizational coordination, ServiceNow study finds.

Whitepaper: Busting the myth that more threat intel feeds lead to better security
It’s a common misconception that a large quantity of threat intelligence feeds leads to more effective security. Unfortunately, threat feed overindulgence can lead to confusion, disorganization, and inaccurate threat reports. Instead of adding more threat intel feeds, you should incorporate the feeds that provide the most value to your organization’s security operations.
