TOCTOU Vulnerability in Lenovo Software Products

CVE-2024-10253

What is CVE-2024-10253?

CVE-2024-10253 is a vulnerability affecting Lenovo's software products, specifically the PC Manager, Lenovo Browser, and Lenovo App Store. This vulnerability is categorized as a Time-of-Check to Time-of-Use (TOCTOU) issue, which potentially allows a local attacker to crash the system. Such an exploit can disrupt operations and lead to unintended downtime, posing risks to business continuity and data integrity for organizations relying on these software solutions.

Technical Details

The vulnerability is rooted in the design of the affected Lenovo software products, where a timing issue can be exploited. Under certain conditions, an attacker could manipulate the state of the system after a check is performed but before the system uses that state. This flaw can create opportunities for privilege escalation or denial of service, mainly affecting local attackers who have access to the system.

Potential Impact of CVE-2024-10253

1. System Crashes: The most immediate impact of this vulnerability is the possibility of system crashes, which can interrupt critical operations and lead to loss of productivity.

2. Increased Downtime: Organizations may experience increased downtime while they address the exploitation of this vulnerability. This can have downstream effects on customer service, data processing, and overall operational efficiency.

3. Potential for Escalated Attacks: Although currently noted as not being exploited in the wild, the nature of the vulnerability could enable further attacks if left unaddressed. This could facilitate unauthorized access to sensitive systems or data if multiple vulnerabilities are present in the environment.
