Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 24 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-48732 effectively, European organizations should: 1) Immediately review and update the .htaccess configuration files used by AVideo installations to ensure a comprehensive blacklist that explicitly denies access to .phar files and other potentially dangerous extensions. 2) Implement web application firewall (WAF) rules to detect and block HTTP requests attempting to access .phar files or exhibiting suspicious patterns indicative of exploitation attempts. 3) Restrict file upload and execution permissions on the server to prevent unauthorized placement or execution of .phar archives. 4) Conduct thorough code audits and configuration reviews to identify and remediate any other incomplete or misconfigured access controls. 5) Monitor server logs for unusual HTTP requests targeting .phar files or other anomalies that could indicate exploitation attempts. 6) Where possible, upgrade to newer versions of AVideo that address this vulnerability or apply vendor-provided patches once available. 7) Employ network segmentation and least privilege principles to limit the impact of any successful exploitation. 8) Educate system administrators and developers about the risks of incomplete blacklists and the importance of secure configuration management. These steps go beyond generic advice by focusing on the specific attack vector and configuration weaknesses identified in this vulnerability.

Description

An incomplete blacklist exists in the .htaccess sample of WWBN AVideo 14.4 and dev master commit 8a8954ff. A specially crafted HTTP request can lead to a arbitrary code execution. An attacker can request a .phar file to trigger this vulnerability.

Impact

For European organizations, the impact of CVE-2025-48732 can be significant, especially for those relying on WWBN AVideo for video content management, streaming, or hosting services. Successful exploitation could allow attackers to execute arbitrary code on the web server, leading to unauthorized data access, modification, or deletion. This compromises the confidentiality and integrity of sensitive video content and user data. Additionally, attackers could disrupt service availability by executing destructive commands or deploying ransomware. Given the nature of AVideo as a media platform, organizations in media, education, and entertainment sectors are particularly vulnerable. The breach of video content or user information could result in reputational damage, regulatory penalties under GDPR, and financial losses. Since the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad. European entities with public-facing AVideo installations are at higher risk, especially if they have not applied mitigations or patches. The absence of known exploits in the wild provides a window for proactive defense, but the high severity score indicates that the threat should be treated urgently to prevent potential compromise.

Base weaknessOWASP Top 10 A03:2021: Injection (opens in a new tab)
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
Implementation · Input Validation
Do not rely exclusively on detecting disallowed inputs. There are too many variants to encode a character, especially when different environments are used, so there is a high likelihood of missing some variants. Only use detection of disallowed inputs as a mechanism for detecting suspicious activity.
