Over Half Of SAP Servers On The Internet Are Vulnerable To Attack, Researcher Says

Critical flaws in leading ERP app to be demonstrated at Black Hat this week

A researcher has discovered a critical set of security vulnerabilities that afflicts more than half of SAP servers on the Internet.

At the Black Hat USA conference in Las Vegas this week, SAP security expert Alexander Polyakov will outline a new issue he has found with the industry's most popular enterprise resource planning (ERP) application, SAP.

The new class of vulnerabilities could enable an attacker to gain control of a company's financial flow, providing the path for espionage, sabotage, or fraud, Polyakov says in a press release.

The flaw, which Polyakov foun in the J2EE engine of SAP's NetWeaver software, allows and attacker to bypass authorization checks. "For example, it is possible to create a user and assign him to the administrators' group using two unauthorized requests to the system, the release states. The attack works even when systems are protected by two-factor authentication.

To prove the vulnerability, researchers from Polyakov's company, ERPScan, created a program that detects SAP servers on the Internet. More than half of the servers detected with this new program displayed the authorization vulnerability.

"During our research, we detected several examples [of the vulnerability] in the standard system configuration," Polyakov states in the release. "And because each company customizes the system under its own business processes, new examples of vulnerabilities of the given class can be potentially detected at each company in the future."

ERPScan is offering a free program that can detect the vulnerabilities.

CVE-2015-20001
PUBLISHED: 2021-04-11
In the standard library in Rust before 1.2.0, BinaryHeap is not panic-safe. The binary heap is left in an inconsistent state when the comparison of generic elements inside sift_up or sift_down_range panics. This bug leads to a drop of zeroed memory as an arbitrary type, which can result in a memory ...
CVE-2020-36317
PUBLISHED: 2021-04-11
In the standard library in Rust before 1.49.0, String::retain() function has a panic safety problem. It allows creation of a non-UTF-8 Rust string when the provided closure panics. This bug could result in a memory safety violation when other string APIs assume that UTF-8 encoding is used on the sam...
CVE-2020-36318
PUBLISHED: 2021-04-11
In the standard library in Rust before 1.49.0, VecDeque::make_contiguous has a bug that pops the same element more than once under certain condition. This bug could result in a use-after-free or double free.
CVE-2021-28875
PUBLISHED: 2021-04-11
In the standard library in Rust before 1.50.0, read_to_end() does not validate the return value from Read in an unsafe context. This bug could lead to a buffer overflow.
CVE-2021-28876
PUBLISHED: 2021-04-11
In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety r...
