Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU97708

Risk: Medium

CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-46303

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input within the ink_to_local_path() function in ebooks/conversion/plugins/html_input.py. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation

Update the affected packages.
app-text/calibre to version: 7.16.0

Vulnerable software versions

Gentoo Linux: All versions

app-text/calibre: before 7.16.0

CPE2.3

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Path traversal

EUVDB-ID: #VU95129

Risk: High

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2024-6781

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in cmd_export.py. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

Mitigation

Update the affected packages.
app-text/calibre to version: 7.16.0

Vulnerable software versions

Gentoo Linux: All versions

app-text/calibre: before 7.16.0
