Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Pandora 在其归档解包工作进程中存在路径遍历漏洞。在处理特制的归档文件或磁盘镜像时，攻击者控制的文件路径可能被直接使用，而未确保目标路径仍位于预期的解包目录之内。 能够提交恶意文件进行分析的攻击者，可以利用路径遍历序列或构造的路径，使解包后的内容被写入指定解包目录之外，从而可能覆盖 Pandora 工作进程可访问的文件。成功利用此漏洞可能导致应用程序或系统文件被非授权修改、服务拒绝（DoS），并取决于 Pandora 进程的权限及可覆盖的文件范围，还可能进一步导致系统被侵入。 该漏洞的修复方式是：在写入前对每

Vulnerability Title
Path traversal in Pandora archive extractor allows arbitrary file writes outside the extraction directory in pandora analysis
Source: CVE Program / CVE List V5
Vulnerability Description
Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory. An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process. Successful exploitation could result in unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten. The vulnerability is addressed by resolving each extraction destination path before writing and verifying that it remains below the expected extraction directory. Extraction attempts resolving outside this directory are rejected and reported as path traversal attempts.
