A vulnerability, which was classified as problematic, has been found in fredsmith utils. This issue affects some unknown processing of the file screenshot_sync of the component Filename Handler. The manipulation leads to predictable from observable state. The name of the patch is dbab1b66955eeb3d76b34612b358307f5c4e3944. It is recommended to apply a patch to fix this issue. The identifier VDB-216749 was assigned to this vulnerability.
The vulnerability has a CVSS score of 2.6, which classifies it as low severity. Although it may not appear critical, it can still pose risks to organizations if left unaddressed. The attack vector is adjacent network, meaning that an attacker must be on the same local network to exploit this vulnerability. This requires low privileges and no user interaction.
Organizations should prioritize patching immediately, especially if they utilize the utils_project component in their systems. Given the nature of the vulnerability, potential exploitation could lead to unpredictable system behavior, impacting reliability and trust.
Currently, no known exploits exist for this vulnerability, and it is not actively being exploited in the wild. Organizations are, however, encouraged to stay vigilant and monitor for any updates or changes in the status of this vulnerability.
In summary, while CVE-2021-4277 may be classified as low severity, it is critical for organizations using affected versions to apply the patch to mitigate any potential risks.
Vulnerability Details
The CVE-2021-4277 vulnerability is associated with the utils_project, specifically the utils component. The official CVE description states that the vulnerability allows for some unknown processing of the file screenshot_sync, leading to predictable behavior based on observable state. This emphasizes the importance of applying the patch identified as dbab1b66955eeb3d76b34612b358307f5c4e3944 to mitigate this issue.
The CVSS score of 2.6 indicates a low severity level. The attack vector is classified as adjacent network (AV:A), suggesting that it requires the attacker to be on the same local network. The attack complexity is high (AC:H), meaning that exploiting this vulnerability is not trivial, and low privileges (PR:L) are required without any user interaction (UI:N).
The potential impacts include a low level of confidentiality impact (C:L), no integrity impact (I:N), and no availability impact (A:N). Organizations should still consider the overall risk to their systems when evaluating the necessity of patching.
Technical Analysis
The root cause of CVE-2021-4277 lies within the processing logic of the screenshot_sync file in the Filename Handler component. When this file is manipulated, it can result in predictable states that could potentially be exploited. The attack vector is adjacent network, indicating that an attacker must be on the same local network to leverage this vulnerability.
The attack complexity is high, requiring a detailed understanding of the system and the ability to manipulate the file correctly to achieve the desired outcome. The required privileges are low, meaning that an attacker can exploit this vulnerability without needing elevated access rights.
There is no requirement for user interaction, which increases the potential for exploitation if the attacker is able to access the local network. However, despite these factors, the overall impact is limited due to the low confidentiality and integrity impact.
Risk & Impact Analysis
Risk to organizations includes potential manipulation of system states leading to unpredictable behavior. While the CVSS score of 2.6 indicates a low severity, organizations should assess their specific environment and use cases to determine the overall risk. The blast radius of this vulnerability may be limited to systems utilizing the affected component, but the consequences of unexpected behavior could still be significant.
Given the low EPS score of 0.002, indicating a low probability of exploitation, the urgency for patching is moderate. Organizations should schedule remediation as part of their regular patch management processes.
Overall, while this vulnerability may not present an immediate threat, it is essential to remain proactive in addressing it to prevent any possible future exploitation.
