Apache Patches Carpe Diem Vulnerability in Web Server Update
Apache HTTP Web Server customers are being urged to replace their servers to patch for a sequence of vulnerabilities within the broadly deployed open-source expertise.
The Apache HTTP Server (generally known as merely “Apache”) is a foundational element of the trendy web and is essentially the most broadly used net server on this planet at this time. The new flaws affect a number of variations of Apache starting from the two.4.17 launch till the two.4.38 replace. The new Apache 2.4.39 milestone was launched on April 1, fixing six vulnerabilities in whole, three of that are rated as being “important” by the Apache Software Foundation.
“Flaw in Apache HTTP Server 2.4.17 – 2.4.38 allows anyone you allow to write a script (PHP, CGI,..) to gain root,” Mark Cox, consulting engineer at Red Hat and VP of Security on the Apache Software Foundation, wrote in a Twitter posting. “Get 2.4.39 *now* especially if you have untrusted script authors or run shared hosting.”

Among the three vital vulnerabilities patched within the Apache 2.4.39 replace is CVE-2019-0211, which is a privilege escalation flaw. The vulnerability was reported to Apache by researcher Charles Fol, a safety engineer at Ambionics Security.
“Apache HTTP suffers from a local root privilege escalation vulnerability due to an out-of-bounds array access leading to an arbitrary function call,” Fol wrote in an advisory.
The CVE-2019-0211 challenge abuses a day by day perform in Apache often called logrotate, the runs as soon as a day to restet log recordsdata. Fol has colloquially dubbed the flaw as CARPE DIEM – CARPE: stands for CVE-2019-0211 Apache Root Privilege Escalation; and DIEM is as a result of the exploit triggers as soon as a day.
CVE-2019-0217 and CVE-2019-0215
Security researcher Simon Kappel is credited by Apache with discovering the CVE-2019-0217 vulnerability which can be rated as being vital.
“In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions,” Apache warned in its advisory.
A race situation is a sort of software program defect the place shared information is accessed by a number of concurrent threads with out correct information entry safety.
The third crucial challenge patched within the Apache 2.4.39 replace is CVE-2019-0215, which is an SSL entry management bypass flaw. The mod_SSL module in Apache is chargeable for dealing with SSL/TLS (Secure Sockets Library/Transport Layer Security) encryption. According to Apache, the CVE-2019-0215 flaw might have probably enabled an attacker to bypass entry management restrictions.
Millions of Web Servers at Risk
According to safety agency Rapid7, as of April 3, there are roughly two million Apache net server deployments that aren’t but patched. Over half of these situations are operating on public cloud and shared internet hosting suppliers.
Bob Rudis, Chief Data Scientist at Rapid7, commented that the CVE-2019-0211 challenge is especially worrisome since it may be triggered with a…
