A vulnerability was found in Facebook Libra Core (Social Network Software) (unknown version). It has been declared as critical. Affected by this vulnerability is an unknown code block of the file language/compiler/ir_to_bytecode/src/parser.rs of the component Inline Comment Handler. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
Libra Core before 2019-09-03 has an erroneous regular expression for inline comments, which makes it easier for attackers to interfere with code auditing by using a nonstandard line-break character for a comment. For example, a Move module author can enter the // sequence (which introduces a single-line comment), followed by very brief comment text, the \r character, and code that has security-critical functionality. In many popular environments, this code is displayed on a separate line, and thus a reader may infer that the code is executed. However, the code is NOT executed, because language/compiler/ir_to_bytecode/src/parser.rs allows the comment to continue after the \r character.
The weakness was shared 09/11/2019. This vulnerability is known as CVE-2019-16214 since 09/10/2019. The exploitation appears to be difficult. The attack can be launched remotely. The requirement for exploitation is a single authentication. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit.
Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
