Path of Bits researcher Andreas Kellas not too long ago disclosed a 22-Years-Previous SQLite bug which has been tracked as “CVE-2022-35737.” The SQLite database library has been discovered to comprise this vulnerability that has a excessive severity stage.
In October 2000 a number of code modifications had been made which led to the prevalence of this high-severity vulnerability. Risk actors may exploit this flaw to crash and management packages in the event that they succeeded in exploiting it.
Whereas it has been confirmed that this extreme SQLite Bug might be exploited on methods which can be based mostly on 64-bit structure. Nevertheless, the extent to which a program is exploitable is determined by the way in which it’s compiled.
Flaw Profile
- CVE ID: CVE-2022-35737
- CVSS rating: 7.5
- Severity: Excessive
- Present Description: SQLite 1.0.12 by means of 3.39.x earlier than 3.39.2 typically permits an array-bounds overflow if billions of bytes are utilized in a string argument to a C API.
Technical Evaluation
Utilizing this subject SQLite Bug, an attacker may execute arbitrary code on the affected system on account of exploiting the vulnerability. SQLite’s printf features require attackers to move massive strings as inputs and the format string comprises %Q, %q, or %w substitutions.
In keeping with the report, The next are the affected variations in addition to the model that has been fastened:-
- SQLite model 1.0.12 was affected by this flaw that was launched on October 17, 2000.
- In SQLite model 3.39.2 the flaw was fastened and this model was launched on July 21, 2022.
This extreme vulnerability has been found in the way in which the string formatting is dealt with by a operate that is called “sqlite3_str_vappendf” and this operate is known as by printf.
When a library is compiled with out stack canaries, the potential for operating arbitrary code is confirmed. However, the presence of stack canaries implies the execution of arbitrary code, whereas DDoS is at all times confirmed in all circumstances.
The SQLite database engine was developed in C and is extensively used at the moment. The next working methods and internet browsers embody it by default:-
OS:
Net Browsers:
- Google Chrome
- Mozilla Firefox
- Apple Safari
The SQLite printf operate will not be weak to widespread assaults in all methods and functions that apply it. Apart from being a really severe vulnerability, additionally it is an instance of a situation that was as soon as thought-about to be unfeasible many years in the past.
