What is the risk?
These vulnerabilities stem from two main issues:
- Use after free in Side Panel Search: This vulnerability allows attackers to exploit memory errors in the Side Panel Search feature, potentially leading to the execution of arbitrary code or the bypassing of security measures.
- Insufficient data validation in Extensions: This vulnerability arises from inadequate validation of data input in extensions, which can be exploited by attackers to execute malicious actions on affected systems.
Cert-In in its vulnerability note says that remote attackers can leverage these vulnerabilities by luring unsuspecting victims to visit specially crafted web pages. Upon visiting these pages, the vulnerabilities will be triggered, allowing attackers to hack into unsuspected users.

Meanwhile, CERT-In is observing “Cyber Swachhta Fortnight” from February 1 to 15, 2024. The aim of this initiative is to ensure the digital security of the country by securing cyberspace from botnets, which can infect and compromise the end user’s systems.
To achieve this, CERT-In has launched the ‘Cyber Swachhta Kendra’ (CSK), which offers eScan Botnet Scanning & Cleaning Toolkit for laptops, desktops and smartphones. This toolkit is developed in collaboration with eScan, a well-known cybersecurity solutions vendor. With this powerful tool, citizens can scan and clean their devices and protect them from botnet infections.
