The archive/zip package's handling of certain types of invalid zip files differs from the behavior of most zip implementations. This misalignment could be exploited to create an zip file with contents that vary depending on the implementation reading the file. The archive/zip package now rejects files containing these errors.
This vulnerability allows for potential integrity impact within applications using the Golang Go library. The CVSS score of 5.5 classifies this as a medium severity issue, suggesting that organizations should address this in their patch cycle.
Risk to organizations includes the potential for inconsistent application behavior and possible data integrity issues when processing zip files. Failure to address this vulnerability could lead to significant operational risks.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
The official description of CVE-2024-24789 indicates that the archive/zip package's handling of certain types of invalid zip files differs from the behavior of most zip implementations, which could allow for the creation of zip files with varying contents. The package has been updated to reject such files.
The CVSS score is 5.5, which is classified as medium severity. This means that while the vulnerability is not critical, it still presents a notable risk that should not be overlooked.
Technical Analysis
The root cause of this vulnerability lies in the inconsistent handling of invalid zip files within the archive/zip package. The attack vector is local, meaning an attacker would need local access to exploit this vulnerability. The complexity of the attack is low; no special skills are needed.
The privileges required are low, meaning that an attacker could potentially exploit this vulnerability with minimal access. User interaction is not required, making it easier for an attacker to execute an attack.
The impact on confidentiality is none, while the integrity impact is high, as the vulnerability could lead to corrupted or improperly handled data. There is no impact on availability.
Risk & Impact Analysis
Real-world deployment risk is significant, particularly for applications that heavily rely on zip file processing. The inconsistency in handling zip files could lead to unexpected behaviors in applications, affecting data integrity.
This vulnerability matters to organizations as it could lead to data corruption or loss, affecting business operations and trust in applications. The potential for a blast radius is notable, especially in environments where multiple applications rely on the same zip processing libraries.
Urgency assessment based on the CVSS score suggests that organizations should address this vulnerability in their priority patch cycle to ensure the integrity of their applications.
