What is the process of a stock audit?

There is a comprehensive guidance on the process of stock audit which help to conduct the audit properly:

Step 1: Plan the Audit

Define the audit scope: types of inventory, locations, and specific items.

Set a timeline that fits the company’s schedule.

Step 2: Conduct Physical Verification

Count inventory systematically using methods like ABC analysis or cycle counting.

Coordinate with relevant departments for the counting process.

Step 3: Compare Physical and Book Inventory

Match physical counts with recorded inventory.

Note discrepancies, investigate causes, and document reasons after discussing with the team.

Step 4: Prepare and Submit the Report

Create a report detailing findings, irregularities, and suggestions for improvement.

Summarize key outcomes for management and recommend necessary actions.

SQL injection | SQL注入

SQLi是一种网络安全漏洞，它允许攻击者干扰应用程序对其数据库进行的查询。这可能允许攻击者查看他们通常无法检索的数据。这可能包括属于其他用户的数据，或者应用程序可以访问的任何其他数据。在许多情况下，攻击者可以修改或删除这些数据，导致应用程序的内容或行为发生持久变化。

在某些情况下，攻击者可以升级SQL注入攻击，以破坏底层服务器或其他后端基础设施。它还可以使他们能够执行拒绝服务攻击。

假设有一个网站URL https://someurl.com/someroute?param=some_value，它返回一组公共数据。当请求此URL时，服务器的中间件会生成一个SQL查询来检索数据：

SELECT * FROM SOMEROUTE WHERE SOME_CONDITION = 'some_value' AND RELEASED = 1

这个查询旨在返回SOME_CONDITION与URL参数中提供的值匹配且RELEASED标志设置为1的数据，表示公共数据。

然而，如果黑客在GET请求的param值后附加'--，它有效地注释掉了SQL查询的其余部分，导致中间件返回所有数据，包括公共和私有数据。修改后, https://someurl.com/someroute?param=some_value'-- 将导致以下SQL查询：

SELECT * FROM SOMEROUTE WHERE SOME_CONDITION = 'some_value' --' AND RELEASED = 1

`--` 之后的内容被视为注释，因此忽略了AND RELEASED = 1条件。

此外，如果黑客将URL更改为https://someurl.com/someroute?param=some_value'+OR+1=1--，他们利用了OR 1=1 始终为真的事实。这导致以下SQL查询：

SELECT * FROM SOMEROUTE WHERE SOME_CONDITION = 'some_value' OR 1 = 1 --' AND RELEASED = 1;

同样，`--` 注释掉了AND RELEASED = 1条件，由于1=1始终为真 (TRUE)，查询返回SOMEROUTE的所有行，忽略任何条件。

应用程序逻辑的颠覆：

想象一下这样的情景, 一个网站要求用户输入用户名和密码进行登录。然后，应用程序使用类似以下查询的方式检查这些凭据：SELECT * FROM USERS WHERE USERNAME = 'username' AND PASSWORD = 'password' 。如果提供的凭据与数据库中存储的匹配，则应用程序会继续进行其他阶段，例如转到主页面。然而，攻击者或黑客可以利用应用程序逻辑中的漏洞来获取未经授权的访问权限。

一种常见的方法涉及操纵查询以完全绕过密码检查。通过输入一个特制的用户名，比如administrator'--，攻击者可以有效地注释掉查询中的密码检查部分。这导致应用程序执行类似于SELECT * FROM USERS WHERE USERNAME = 'administrator' -- AND PASSWORD = ''" 的查询，从而允许攻击者无需有效密码即可登录。

此外，攻击者还可以利用UNION关键字执行SQL注入攻击，并从数据库中的其他表中检索敏感数据。例如，如果应用程序通常查询SELECT NAME, DESCRIPTION FROM PRODUCTS WHERE CATEGORY = 'GIFTS'来显示可用产品，则攻击者可以注入一个UNION SELECT USERNAME, PASSWORD FROM USERS 的语句，将结果与用户凭据合并。这将允许攻击者从数据库中提取用户名和密码。

SELECT NAME, DESCRIPTION FROM PRODUCTS WHERE CATEGORY = ' GIFTS ' UNION SELECT USERNAME , PASSWORD FROM USERS

对于开发人员来说，实施强大的输入验证和参数化查询至关重要，以防止此类攻击，并保护敏感数据免受未经授权的访问。定期进行安全审计和测试可以帮助识别和解决应用程序逻辑中的潜在漏洞。

成功的SQL注入攻击会有什么影响？

成功的SQL注入攻击可能导致未经授权的访问敏感数据，例如: 

• 密码。

• 信用卡详细信息。

• 个人用户信息。

多年来，SQL注入攻击已被用于许多高调的数据泄露事件。这些事件造成了声誉损害和监管罚款。在某些情况下，攻击者可以获得组织系统的持久后门，导致长期妥协，可能长时间不被发现。

如何检测SQL注入漏洞?

您可以使用一套系统的测试手动检测每个应用程序入口点的SQL注入。为此，您通常会提交：

• 单引号字符'并查找错误或其他异常。

• 一些SQL特定语法，评估入口点的基本（原始）值和不同的值，并寻找应用程序响应中的系统差异。

• 布尔条件，如OR 1=1和OR 1=2，并寻找应用程序响应中的差异。

• 设计用于在SQL查询中执行时触发时间延迟的有效载荷，并寻找响应时间的差异。

• 设计用于在SQL查询中执行时触发出站网络交互的OAST有效载荷，并监视任何结果交互。

或者，您可以使用Burp Scanner快速可靠地找到大多数SQL注入漏洞。

查询中不同部分的SQL注入

大多数SQL注入漏洞发生在SELECT查询的WHERE子句中。大多数有经验的测试人员都熟悉这种类型的SQL注入。

然而，SQL注入漏洞可以发生在查询的任何位置，以及在不同的查询类型中。SQL注入出现的一些其他常见位置包括：

• 在UPDATE语句中，在更新的值或WHERE子句中。

• 在INSERT语句中，在插入的值中。

• 在SELECT语句中，在表名或列名中。

• 在SELECT语句中，在ORDER BY子句中。

SQL注入示例

有许多不同情况下发生的SQL注入漏洞、攻击和技术。一些常见的SQL注入示例包括：

• 检索隐藏的数据，您可以修改SQL查询以返回额外的结果。

• 颠覆应用程序逻辑，您可以更改查询以干扰应用程序的逻辑。

• UNION攻击，您可以从不同的数据库表中检索数据。

• 盲SQL注入，您控制的查询结果不会在应用程序的响应中返回。

• 检索隐藏数据，您可以修改SQL查询以返回额外的结果。

• 颠覆应用程序逻辑，您可以更改查询以干扰应用程序的逻辑。

• UNION攻击，您可以从不同的数据库表中检索数据。

• 盲SQL注入，您控制的查询结果不会在应用程序的响应中返回。

二阶SQL注入

一阶SQL注入发生在应用程序处理来自HTTP请求的用户输入，并以不安全的方式将输入纳入SQL查询中。二阶SQL注入发生在应用程序接收来自HTTP请求的用户输入并将其存储以供将来使用时。这通常是通过将输入放入数据库来完成的，但在存储数据时不会出现漏洞。稍后，在处理不同的HTTP请求时，应用程序会检索存储的数据，并以不安全的方式将其纳入SQL查询。因此，二阶SQL注入也被称为存储型SQL注入。

二阶SQL注入通常发生在开发者意识到SQL注入漏洞，并因此安全地处理输入数据至数据库的情况。当数据稍后被处理时，由于之前已安全地存放在数据库中，它被认为是安全的。此时，数据以不安全的方式被处理，因为开发者错误地认为它是可信的。

检查数据库

SQL语言的一些核心特性在流行的数据库平台中以相同的方式实现，因此许多检测和利用SQL注入漏洞的方法在不同类型的数据库上工作方式相同。

然而，常见数据库之间也存在许多差异。这意味着一些检测和利用SQL注入的技术在不同平台上的工作方式不同。例如：

• 字符串连接的语法。

• 注释。

• 批处理（或堆叠）查询。

• 特定平台的API。

• 错误信息。

在你识别出SQL注入漏洞后，获取有关数据库的信息通常很有用。这些信息可以帮助你利用漏洞。

你可以查询数据库的版本详细信息。不同的方法适用于不同类型的数据库。这意味着如果你找到一个特定的方法有效，你可以推断出数据库类型。例如，在Oracle上，你可以执行：

SELECT * FROM v$version

你还可以识别存在哪些数据库表，以及它们包含哪些列。例如，在大多数数据库上，你可以执行以下查询来列出表格：

SELECT * FROM information_schema.tables

不同上下文中的SQL注入

在之前的实验室中，你使用查询字符串来注入恶意SQL有效载荷。然而，你可以使用任何可控输入来执行SQL注入攻击，只要应用程序将其作为SQL查询处理。例如，一些网站接受JSON或XML格式的输入，并使用这些输入来查询数据库。

这些不同的格式可能提供了不同的方法来混淆攻击，这些攻击由于WAFs和其他防御机制而被阻止。弱实现通常会在请求中查找常见的SQL注入关键字，因此你可能能够通过编码或转义禁止关键字中的字符来绕过这些过滤器。例如，以下基于XML的SQL注入使用XML转义序列来编码SELECT中的S字符：

<stockCheck>

    <productId>123</productId>

    <storeId>999 &#x53;SELECT * FROM information_schema.tables</storeId>

</stockCheck>

这将在服务器端解码，然后传递给SQL解释器。

SQL注入速查表

1. 字符串连接: 不同的数据库有不同的字符串连接语法。例如，Oracle使用’foo’||‘bar’，而Microsoft SQL Server使用’foo’+‘bar’。

2. 子字符串：您可以从指定的偏移量提取字符串的一部分，具有指定的长度。在所有数据库中，偏移索引都是基于1的。

3. 注释：注释可用于截断查询并删除跟随您输入的部分。不同数据库的注释语法不同，如Oracle和Microsoft使用–comment，MySQL使用#comment。

4. 数据库版本：您可以查询数据库以确定其类型和版本，这对于制定更复杂的攻击非常有用。

5. 数据库内容：您可以列出数据库中存在的表及其包含的列。这通常使用information_schema.tables和information_schema.columns来完成。

6. 条件错误：您可以测试单个布尔条件，并在条件为真时触发数据库错误。这对于盲SQL注入非常有用，其中结果不直接可见。

7. 不同上下文中的SQL注入：SQL注入可以使用应用程序作为SQL查询处理的任何可控输入来执行，不仅仅是通过查询字符串。

So what's day in the life of everyone favorite grumpy medic?

7:30am - Up. Coffee/shower, daily news. 8:30am - Check on patients in the ward for breakfast (liasing with whoever is on kitchen duty that day), medicine and run down on healing progress, morning call on discharged patients for follow-up reminder. First Aid comes in. 9:00am - First explosion of the day (Wheeljack) 9:30am - Morning break. Brief reading of new medical journals 10:00am - Check on Wreckers 11:30pm - Check on Dinomachae (Dinobots) 1:00pm - Lunch, catnap 2:00pm - Back in the ward, patient check and lunch call 2:30pm - Second explosion of the day (Brainstorm) 3:00pm - Post-Training Session checkups 5:00pm - Follow-up appointments 7:00pm - Coffee, dinner, shower, 7:45pm - Stockchecking, liasing with suppliers on medical items required. 8:30pm - Third explosion for the day (HotRod) 9:30pm - Lights out for warded patients. 9:45pm - Practical emergency/surgical sessions with First Aid 11:45pm - First Aid leaves, personal research and daily review 1:00am - Leisure time, may head to Swerve's if open. 2:00am - Warded Patient check, recalibrating instruments and devices for next day. 2:30am - Crash

This is assuming it's a standard day at the base and not in the middle of active combat, at which point he probably forgoes food unless reminded and has gone on seventy-two hour stretches with no sleep outside of little catnaps.

Funny mental image for you: Jocasta finds out Dooku stole a bunch of holocrons on his way out of the Order when doing a stockcheck after learning Kamino was deleted. Gatecrashes the execution on Geonosis, accidentally stealing Mace's thunder when she goes for her old friend with fire and brimstone and Mace, very wisely, takes three large steps back to give her all the space she needs to tear a strip out of Dooku up one side and down the other about fucking with her archives. Lightsaber optional.

Oh wow, yes please.

Why do we need stock auditing?

Stock auditing is important because it helps businesses keep track of their inventory. By regularly checking stock levels, businesses can:

Identify discrepancies: Find and fix any differences between the recorded stock and actual stock.

Prevent theft and fraud: Spot and stop unauthorized access to inventory.

Ensure accurate records: Maintain correct inventory records for better decision-making.

Optimize inventory levels: Avoid overstocking or understocking, leading to better resource management.

Comply with regulations: Meet legal and financial reporting requirements.

'Tomorrow' was something of an optimistic timeframe; Setsyn, despite her promises, did not have an update waiting for Eirnhaya the next morning. It was mid-morning before she deigned to answer her holo, by which point Eirn had realised (and Quinn had intimated at least twice) it would have been quicker to go a speak to the woman in person, and even then all she had to say for herself was a spirited defence of her status as Baras's most trusted operative on Nar Shadaa.

Eirn was actually rather surprised, watching that conversation, that Setsyn hadn't gagged on those words; either Quinn was working on being a different model of Sith to his Master, or was yet to master the art of the remote Force-choke. She honestly wasn't sure which one would be better; certainly, Baras would likely have preferred his apprentice be every millimetre the Sith he was, but that would at least make him predictable.

Lacking any desire to get under Quinn's feet, Eirn ended up sequestering herself away in the medbay - busied herself with a stockcheck, perusing their supplies and familiarising herself with the layout as she checked their records and, where necessary, updated them. Someone, she noted, had been helping themselves to the kolto gel without updating the stock; there were only two possible culprits, and both of them had good cause and the presumable unfamiliarity with Imperial procedure that would result in the count being off. Arrogance, ignorance, same difference.

She was joined, partway through her task, by one of the suspects - who promptly parked herself on the bed, playing illegal music on her holo and snacking on what looked like dried ziiberries.

'Hello, Vette,' Eirn mused, smiling a little to herself. 'To what do I owe the pleasure?'

'His Lordly Sithyness is sulking,' Vette harrumphed, 'And you're better company than the droid.'

Which Eirn wasn't entirely certain was a compliment, but she took it anyway. 'Sith do not sulk, Vette,' Eirn replied, though - they brooded, they meditated. (They sulked.)

'They do,' Vette retorted, 'And you know it.'
