CVE-2025-9497 is a medium-severity vulnerability affecting Microchip Time Provider 4100, prior to version 2.5.0. This vulnerability allows the use of hard-coded credentials, which could enable malicious manual software updates. The CVSS score of 5.5 indicates that while the risk is moderate, it still poses a significant threat that organizations must address.
Risk to organizations includes potential unauthorized access and manipulation of software through the exploitation of hard-coded credentials. The complexity of the attack is categorized as high, requiring elevated privileges for execution, which underscores the need for immediate attention by security teams.
As of now, the vulnerability status is awaiting analysis, and there are no confirmed public exploits. Nevertheless, the urgency for defenders remains high, as attackers may leverage this vulnerability for unauthorized actions if left unaddressed.
Organizations should prioritize patching immediately to mitigate the associated risks and protect their infrastructure from potential exploitation.
Vulnerability Details
The CVE description specifies that the vulnerability lies in the hard-coded credentials of the Microchip Time Provider 4100, allowing for malicious software updates. The affected versions are all prior to 2.5.0. The vulnerability is categorized as CWE-798, indicating the use of hard-coded credentials.
The CVSS version 4.0 score is 5.5, indicating a medium severity. The attack vector is local, requiring high privileges and presenting a high attack complexity. The integrity impact is high, while confidentiality and availability impacts are low.
Technical Analysis
The root cause of this vulnerability is the presence of hard-coded credentials, which can be exploited by an attacker with high privileges to perform malicious updates. The attack vector is local, necessitating physical or network access to the device, while the attack complexity is high due to the requirement for specific privileges.
User interaction is not required for the exploit to be executed, making it more dangerous. The potential impacts include high integrity loss, while confidentiality and availability are assessed as low.
Risk & Impact Analysis
Real-world deployment of the Microchip Time Provider 4100 with this vulnerability poses a risk of unauthorized software modifications that can lead to compromised operations. This could extend to all systems utilizing the Time Provider, increasing the blast radius of potential exploits.
Organizations utilizing this technology should be aware of the potential impact on their operational integrity and prioritize remediation of this vulnerability based on its CVSS score of 5.5.
Given the current lack of active exploitation reports, organizations should still prepare for the possibility of future incidents and address this vulnerability in their patching strategies.
